Ides, Ides, Ideas

I recently got my first car, its a 1994 Ford Taurus. I have a few things i plan to do which i would like some advice on...

My exterior is a off white tan color, and my doors have black trim.. Well at least at one point they did, now they have 'scratch trim' i was going to try to spray paint over the scratches - good idea, bad idea? How would i do this, just put tape over the border of the window and the black trim?

I had an aftermarket cd player put in, and it works wonderfully ... only problem is, it slides right out and im not really sure why. (I put it in myself.)

The inside of the car is pretty dirty ... i tryed the good ol' scrub like crazy, but thats not working. Does anybody know what i should use to clean it ... What do i use for the seats, what do i use for the dash etc...

Lastly I was wonderin how yall felt about interior lights .. i was going to get neon lights to go along with my subs once i get around to getting subs, i was also going to get blue vents with a blue wheel cover ... then i decided i wanted to keep the car looking clean ... Opinions please?
