Swamp,
I think that ou have the right idea about where to start as for as your class. In my opinion you shold go to the WERA website for most of the questions you are asking. Safety wiring is not that hard but there are technics for axle nuts, caliper bolts etc, etc.
I posted, some time ago, a diagram for safety wiring on the NESBA web site so you could search for that if you needed but really the WERA site is the best place to go.
I don't know if you have done an Ed Bargy race school or not but it is really worth while and at the end of the day there is a mock race. Also, you get a good rate for practice laps while the school is being held. Go to Ed's website for info.
Good Luck!
