Would it void warranty or jeapordize it if you went to a garage or elsewhere to get the 30k maintenance done? That 349.00 sounds kind of steep.

Also, can I get a complete list of what is done besides:

check brakes and calipers
Inspect fluid levels
rotate/balance tires
lube gears

 

It will NOT void the warranty. As long as you can prove that each of the services required at 30K was performed your warranty will stay intact.
