It's not generally referred to by "heat", more a color temperature.

Stock is 4300K
Yes, you can change the bulb to a different color (ie, 6000K, 8000K)
I believe stock is 35watts
Depending on which generation it could be D2R, or D2S.

can you also change the bulbs with out taking teh lights off the car?

 

If you want to swap out the HID bulb for a different color, you'll want a D2R bulb.

Yes, you can change the bulb without removing the light housing from the car.
