...or you can buy same kit on ebay for like $40
and if you got little understanding of how put few connectors together yes you can do it in few hours. If you want best quality from HID, go with Phillips but they cost more, plus you probably know how it works: you get what you pay for.
The other thing is stock headlights with an HID kit is probably not going to give you the same light distribution and pattern as real a HID headlight because they are simply not made for the HID bulb. You may be surprised but some headlights will have better light distribution with a stock bulb than with an HID bulb. On another note, if the car uses the same bulb for both high and low beam than you will lose your high beam unless you will buy bi-xenon HIDs.
And don't be disappointed if you install an HID kit that it will look cool and bright when you going to be standing on front of the car, but when you will be driving it at night you are not going to see anything.
Stay away from aftermarket projector headlights like you will see on ebay or any other store; yes they look nice but the quality of light is very poor. If you want good HID projector lights you will need to buy real HID projector (projectors for HID are different from projectors with halogen bulb) and fit them to the headlight housing which takes a lot of time and knowledge but the end result is high quality real HID light.
And on temperature get 6000k which is crystal white or 8000k which are bit more blueish anything lower than 6000k will be yellow (like for fog lights you can use 4500k which are yellow) and anything more than 8000k will be to blue and want light the road up very good
