Buy a roll of B50 bowstring from an archery supplier.
So you may want to ask the local archery club if there is any near you

and the books, you may want to try the local small book seller with the title (traditional bowyer's bible), the author (Jimm Hamm, anyone to correct me ?) and the ISBN (1585740853, to make it easier).
Or if you are in the middle of the ocean, you can try amaizon, it's easy to find with a goolge search.
and the cheap pine sharft, you may find it at the same place you found your saw
