I would suggest to get some books by Larry Wise, I'm sure you can get them on amazon, which explains pretty much everything on compound bows.

If you are looking for a press, look at Apple. I have one that cost around $100 I think. Always use the safety strap around the bow before tightening. As long as you do this, if something slips, it should still be safe.

As far as arrow, I would suggest a Bitz, and just follow the instructions.
