As for a HID kit .. I'd go with these
http://www.ddmtuning.com/Products/Ap...Raptor-HID-Kit
I have them in my bike and they are awesome. I run the 35w 4500k so it looks white and 55w do run a bit hot. Thats why I only went with 35w ones. Quiet a few run the 55w on their bikes and say they have no problems. Some also suggest putting in a switch so they don't draw power while trying to start the bike. Eh I didn't and my bike starts fine.
This thread on a honda cbr site is why i went with the kit so you can see a little compairison between types.
