As far as getting some carbon parts, you can check out some of the vendors on the site here and just have it installed at a local shop. The hood should be easy to install so you can do that yourself. As far as aftermarket bumpers go, it'll probably look weird without the full kit.
There's also these performance shops that can probably order those for you too:
AWDTuning
2807 Justin Road Flower Mound, TX 75068
JoTech
3513 Dividend Drive, Garland TX 75042
Pro Tuning Performance
3333 Suffolk Dr. #202, Ft. Worth, TX 76133
Pro Tuning Performance - Dallas Fort Worth's Premier Road Race Performance Center - Homepage
There's also Baker tuning in Houston but not sure if you want to go that far. I'm sure the shops I mentioned can refer you to a good bodyshop to repaint your existing stuff if you want that or paint any new parts you order.
