My Red BRAKE light just came on and the "check brake lining" message displays when I turn off my engine.* I have 37k miles and believe my front brakes need replacement.* I don't have time to DIY, so I will take it into an INDY.*My INDY quote is $600 for the brake job including labor.* Is this price high?

Should I purchase my brake stuff online and take it to them? I believe labor is 1.5 hrs = $135.00
Are the name brand brakes purchased on the internet better than the OEM ones my indy usually carries from the dealer?
What do I need to buy? Any recommendations for good quality brakes/rotors/etc?
Thanks in advance.
