Should i get all this stuff?

Wow, you clearly have some cash to drop. Anyways, if you're going to be spending all that money I suggest you drop the kit lens and get the 17-40mm L. Also, I'd see about getting the f/2.8 version of the 70-200mm. If you're doing wildlife I'd try to keep the 100-400mm. If you need to cut anything to save money, I'd probably suggest the battery grip. This depends on your needs, but I personally would downgrade the speedlight to the 430EX to spend the extra money on the lenses I suggested.
