I wouldn't use the 55w as they are pretty bright. I have the 8k 35w and work and look fantastic with the CB MS3. As for the fogs.. I just kept them stock with some yellow overlays for them.
If you use a 55w kit in a small space your asking for melt down...I would HIGHLY recommend you going with a 35w that way it's truer color and no wash out...just my 2 cents.
I went with 3k 35w slim ballast and i absolutely love them. I just ordered lamin-x covers to make them more yellow.
Not to mention yellow is a typical color for fogs because yellow doesn't reflect light from dust or fog.
i think i might try retrofitting my foglights with lexus es300 fog projectors when i have the time
my friend gets them from the junkyard he works at and has it done to his si
looks kinda like this
