The tank comes off with a bolt under the seat. Don't forget to turn the petcock to "off" and disconnect the fuel line.
Taking the front fender off is real easy, taking side covers off is real easy (one just "pops" off and the other has two screws)
haven't had the rear plastics off but it looks really simple, maybe 4 bolts?
as for how to make it look bad-ass, i'd suggest reading through a bunch of the threads here, as there are some downright awesome looking bikes around
