How to sell my car quick?

Hey,
I was just wondering if any of you have experience selling older Honda's? I'm going to be puting mine up for sale this summer and want to know if it is worth fixing certain things. I'm planning on puting it up on some online car ad places like Carsoup or Autotrader and have a link to my website for additional pics.

I've got rust on the rear wheel fenders like most cars my age and alot of little chips and scratches... should I try to get this stuff fixed and dump money into the car before I sell it?
Are people going to pay more for my stereo(which is very nice) or should I pull it out and sell everything on ebay?
I have a set of 96 HX alloys also, should I sell them to a friend and get his stock steel wheels before I sell it or sell it with the rims?

any advice would be great, I've never sold a car before.
thanks

BTW it has 156k miles on it and I'd like to get about $3500 for it
does that sound decent?
