Read about my clutch install ordeal here.

This should be all the info you need, I ended up installing the transmission by myself with no special tools, only a jack, with the engine just like it is, not jacked up.
All in all it took about 5 days, about 4 hours to get to the point where the transmission is off, a couple hours to get the flywheel resurfaced/get the clutch torqued down and the throwout beaing in. And then 4 days to reinstall.
If I had done it my way from the beginning I would have been done in under 10 hours, first time with no FSM. Now I could probably do it in 6-7 total.
