Clutch throw out bearing/ clutch questions.

Alright, I've done a bit of searching and I'm almost positive my problem is in my throw out bearing.... awful squeal when I press in the clutch, and rpms drop to about 500... damn near dies when I go into reverse. Also, my wagon grinds hard going into reverse, and makes an unusual amount of that.... reverse gear whine, a lot more than any other car I've driven. Even using that 2nd gear, then reverse gear trick I saw on here, its still bad, any ideas? And finally, I'm thinking I should be able to find this by a search but I haven't had any luck yet.... will the 5th gear from my HF crx fit into my RT4WD wagon?
