This will walk you though it. A truly excllent resource.

actually need is a knife. Search for some of Hellfire's posts to see bow's made with just knives and that have been exclusively floor tillered.
Awesome graphic:
http://residents.bowhunting.net/sticknstring/brdbows2.htmlAnd of course, one of your best resources is right here. Several members here (Hellfire, Johnny, English and myself to name a few) have made bows and can answer any questions that didn't come up in the site I just gave you.
The process really depends a lot on intuition and good guesses. I built my first bow from the websites I just gave you and along the way had to stop myself and think for a little bit about something that came up unexpectedly.

Now about cutting the handle of your bow for the arrow. Short answer: no. Long answer: some bows mostly ones which have risers and such do make it possible for the arrow to pass unobstructed. A properly spined arrow however, goes through what is called "archer's paradox" where the arrow flexes just the right amount around the bow going straight despite the apparent deflection.
The string does not need to be offset to one side. It should be directly in the center. If you'd like to move the string for some specialized reason, certain knots are employed.
All in all, a nice attempt at a bow for not knowing anything about them and without access to better resources
