Terribly rude of me to post this and then not answer the questions you asked.

The problem was apparantly that the clutch and gear plate had welded to together (i'm paraphrasing what a mechanic told me) So I bought a used transmission, and have installed it, with some help from my brother and my cousin. It runs great now, though I've got a leak around my axle, that should be corrected when I buy the new axle for it.
