I would buy a shit load of parts. If you play out a lot, things wear and break. Make yourself a little tool kit, and have some felts, springs, Lugs, spacers, you name it. It helps out a lot at shows if you lose pieces.
one thing I just picked up for about 20 is a tourque wrench tuner, and while it doen't have the tourque ( ft lbs) to totally tuner your drum it will get em nice and even on the low end and then a few half turns and your good.
and with the 45 reamining I'd get a nice stick bag
