Not too long ago I posted and got a lot of really good help on doing my brakes.

Questions:
How difficult is it to actually do the change?
How much upper body strength is required?
How much do the tools run?
How much time for someone who has never done this before and will not have any backup should she get into trouble?
I may just take it to the dealer, who actually had the lowest quote so far but you guys bit me with the tinkering bug.
I also found a nice exploded view of the timing belt area here (just scroll down a bit).
