I went through this when rebuilding a 5spd about three months ago. I bought a rebuild kit from Autozone that had all the correct bearings (good quality Koyos), seals, and the gasket for the front cover. They also have repair instructions that I used and they were real close to correct for me. I own several pullers, and now a new shop press (another story that involves a transmission), but only used a cheap puller to do mine. Just take your time, stack the gears, spacers, bearings, etc in the order they come off, facing the direction they came off, or put scribe marks on them to keep them facing the correct direction. I dont remember having to use heat to get anything apart or together, but sometimes it helps. If there is a transmission shop near you, they can help with the pressing on/off of bearings if you cant do it yourself. Here is a link to the Autozone kit, and on the same page is a link to the detailed diagrams and repair instructions.
