I would look into name brand headlight bulbs like Sylvania Silverstar Ultras or GE Nighthawk Sports. I have both; the Silverstar Ultras are in my Camry now and are excellent but can be pricey and they will not last as long as factory bulbs. I also have the 'original' Silverstars in my mom's Camry which are now 4-5 years old. YMMV on bulb life, it's up to you if it's worth the price. I also bought a pair of the Nighthawk Sports when they were on asle at Amazon but haven't used them yet - they're supposed to be good too.
As far as wheels, I went for factory rims in the same tire size so it was a direct swap. Even if you decide to go aftarmarket, it won't void your warranty so long as your modifications weren't the cause of the failure, like improper installation or the wrong size rim. Factory rims just look the cleanest if you're looking to keep the stock look.
Enjoy your new Camry! Welcome to TN
