So following my recent complications with pedals, I'd like to know, once and for all, how tight should I tighten bolts and parts?

I generally tighten things as tight as possible or to the point that I feel should be fine, but thats not very reassuring. So far I've been told about 30 ft.# for crankarm bolts. What about the others? I'm gonna start getting anal about all this and buy a torque wrench. So how many ft#'s should I tighten things?

Seatpost, stem, crank, chainring, pedals, hubs?
