All the parts you picked out will do just fine, and because theyre all middle-of-the-road type stuff, it will give you a good sense of what youll want to change in the future (i.e. deck size and shape, wheel hardness, etc.)
The only thing is, as a snowboarder, I assume youll probably be bombing hills and stuff..so I would go with indys (stage 11 139s) just because they turn so well and they will last a lot longer than thunders. Besides..indy hardware on thunders is sort of weird. Depending on your budget, check out Shorty's hardware and Black Magic grip..those to me are the best.
