Those are some indepth questions. haha. Lets pick them apart.
1. That post would be to long... Your best bet is to google a manual for it.
2. There are a great deal of amazing old 35mm cameras. They usually were built like tanks. I still use a Pentax MX manual camera. Beautiful 35mm camera, that has a meter in it that is tack on still after all these years. If the camera is in good condition it will work amazing. Just make sure the shutter is working properly, and there are not any light leaks.
3. Films well that all depends on what you want to shoot. Black and white, color, or chromes. Send that info my way and I can help you out. The entire fuji line is great, so is kodak really depends. Do you like saturated colors, high contrast, flat colors, etc.?
Sorry to answer you question with more questions but we need to narrow things down a little. Would be happy to help you out though.
Eventually if you get hooked on film which I am sure you will, you should move up to medium format film. (hasselbad) Thats for another day.
