FX-Rs are better quality but require free hand cutting of your light housing and a slightly more difficult aiming/securing process.
Blazers are for fogs, you have to cut/rig it up custom, no plug n play or bake n reseal there.
H10 fogs (H11 for 2012s) are the sizes you need and the harness will be the H4/9003 iirc
H1 has been deemed a little brighter while D2S more even output. Most go with the H1 simply because its brighter but don't consider other factors. Matt and the guys at TRS mostly favor the D2S and I also like to point out that the larger shrouds fill our headlights better than the mini H1 and there is a greater selection.
3000k is yellowish and good for fogs for its ability to cut through adverse weather
4300k is like sunlight or stock color headlights and has the highest lumen count (brightest) of the available options
5000k will be whiter and is the highest TRS recommends.
6000k is also very white with a tiny bit more blue
Any higher temp is stupid because you lose light output and fatigue your eyes and others.
I always say 4300k is the way to go but can see how white/5000k has an appeal
The upside to a projector retrofit vs cheap hid bulbs in your stock light housing is mainly that it is higher quality and has a clean cut off line. Also helps that it is legal.
I can't think of anything else off the top of my head but that should be a good starting point for anyone who wants to start researching these.
