P Magic can get GXP parts ha. But you can check out GMpartsDirect.com they sell all new parts at warehouse prices. Worth a shot! There's a thread here somewhere that listed all the part numbers I'll see if I can find it.
Heres that thread. Hope it helps!
EBay has grills and such, are you looking to do stock headlights or get aftermarket projectors? I'd say get the HIDs from DDMtuning. A trusted source for quality HID lights.
Not sure about the hood, but I'm sure more info will come in from others.
