well all had spears and that was standard but as far as that the list is long. 

Slings were never used in Mainland-China (not including Tibet)  but of course they used all sorts of bows, swords and spears.

What period of China are you talking about?

My friend once had a huge tome of Chinese militairy history. Seems like they kind of went backwards there. They started out with bronze chestplates, shields, bright uniforms, and all sorts of nasty looking blades and polearms. But by the 1600s, they barely had pants and a bamboo pole.

Barely had pants?  Chinese were way advance even at 1600 B.C.!

Hmmm that post was full of Typo's...

I am not big on the classical Greeks, but here is what I recall.

The 'Spartans' used the same weapons as the rest of the Greeks. If you are referring to the 'classical' Spartans, the ones that fought at Thermopylae and Plataea... 

The spear was an 8-foot long thrusting spear
The sword was called a Xyphos, they also used a Kopis
The armour was layers of linen cloth sized with glue and stuck together - it ends up with a texture like wood, but is springy - they called it a Linothorax.
Helmets were Iron, or Bronze, as it's easy to shape
The big round shield was called a Hoplon. Soldiers were called Holites, and if you wanted to disarm a people you took their shields away. They could keep their swords and spears, but no shield meant no war - The Phalanx did not work without shields.

Some armour was reinforced with leather plates, or metal plates in little pieces sewn or riveted to the linen. We are guessing here, from pottery pictures. Linen armour rots, none has been found.

This is the 'heavies - the guys who would have formed a line 8 men deep, with their shields overlapping and gone for the enemy like a Giant battering ram.

Light troops were very important, as the Phalanx was slow and clumsy, and only worked from the front. Hit a phalanx in the side or rear and it is toast. So, to protect the flanks Light troops acted as skirmishers. Slings, Javelins and Bows were all used. They had some horses, but not many. Most light troops would have been poor people that could not afford to buy Linothorax/Hoplon/Xyphos and Spear. It has been calculated that the cost of equipping yourself as a Hoplite was about comparable to the cost of Buying a Ferrari would be today - IE You needed to be pretty well off.

Later there was a stunning victory in which a Spartan Mora was surrounded by light troops armed with small shield and Javelin, shot to bits for hours and then, when they were knackered, finished off close-up. The light troops were called Peltasts (again, after their shields, the crescent shaped Pelta) and most peltasts were mercenaries. They took off in a big way - its a lot cheaper to fight as a Peltast than as a Hoplite.

Want any info for the later Greeks - IE Alexander and onwards? That I DO know a lot about!

The Asians were the ones who came up with the crossbow. It made its way to Europe via the Silk Road, that linked the 2.
   It was so affective in battle, that the church actually banned it, as being "unGodly, and unfair" for use.
  However, during the Crusades, the church allowed it to be used, but, only against the Muslims, as they were not Christians. Apparently that was alright.

Chinese weapons:
 Standard infantry arm across all periods is the spear.  It is quick to produce and little training is needed for peasant levies.
 Standard infantry missile weapons has been, for peasantry, the crossbow.  This has more than adequate penetration, is easily accurate, and in the pre-Han period to the middle of the Tang, crossbow mechanisms were manufactured with inter-changeable bronze parts.  The crossbow has a long draw, almost from the end of the stock where the bow is placed to the other end, on a stock over a foot long.  The early Chinese crossbow stocks frequently had pistol grip handles, and the locks were quite possibly the best in the world from around 600BCE, when they were first manufactured, to the 17th century in Europe, when new advances made very complicated mechanisms possible.  (More about this later.)  There are, in fact, many mechanisms which have survived and because they are bronze and remain un-corroded, they are still useable today, more than 2000 years after their original use.
 Missile weapon for the higher-up folks was the composite bow, which has varied somewhat throughout history in China, from small, light cavalry bows with short siyahs (ears on the recurves) to the giant Qing (Manchu) infantry and cavalry weapons with very long siyahs from the 16th century onwards.  Most bows were recurved to a C shape when unstrung and were made of differing amounts of horn, sinew, wood, birch bark, silk, lacquer and other ingredients.
 Other weapons include swords and halberds.  The ancient Chinese halberd (and double bladed halberds) were made of bronze, with a long horizontal blade and a shorter vertical blade on the end of a long pole.  It was a good infantry and cavalry weapon, and there are many surviving examples, because, as with the bronze swords and crossbow locks, they have not corroded.
 In fact it is somewhat correct to say that many of China's innovations have gone backwards.  Much of the bronze working tradition was lost in the latter half of the Tang dynasty, and later the Yuan (or Mongol) dynasty of China caused a medieval Cultural Revolution, and much of China's traditions of weaponry were lost (ie, the manufacture of crossbows by native Chinese for native Chinese was forbidden, and bamboo was strictly controlled so that bows could not be easily manufactured.)  The Ming dynasty, the third of China's Golden Ages (or possibly the fourth, if one believes that that the Zhou dynasty was as noble and wonderful as Confucius and other believed), had lost the bronze working technology for making crossbow locks had been around about 1300 years before them.  They used simpler, all wood, bone or antler mechanisms, which, although powerful and accurate, frequently failed during use.  Also, repeating crossbows, the earliest of which found comes from 250BCE, were still in use up to the Boxer Rebellion (1900).
 Sword technology was also less advanced, although I know slightly less than bugger all about swords, so I'm sorry I can't provide more information.  In any case, Chinese weapons technology, at its height, could be considered the best in the world, although the later dynasties' loss of the technological traditions could be said to have undone earlier gains.
 If you have any questions, don't hesitate to ask.
