i'm looking to get the prelude h22a and manual transmission for my 92 accord. i had a few questions:

1) how do you find a reputable place to buy the parts from?
2) how much should the h22 and tranny cost?
3) how do you know the parts are in good condition?
4) how do you find a reputable shop to do the installation?
5) how much should the installation cost?
6) how long does the installation take?
7) are there compatibility issues with my i/h/e? i remember reading a long time ago that one would need to buy new parts that were for the h22. is that right, or can i keep my bolt-ons?

thanks for any advice you guys can give
