A lot of people seem to compress and EQ to get their track to sound like they hear on the radio etc, little do they realise there is more to it than that. I would say the most important part would be to get a good input, and then your golden.
Sh!t in, Sh!t out. Not easy to polish a turd, but it is easy and a lot more satisfying leaving a track alone completely because your recording techniques deemed it correct.
Attenuate to make things sit better, boost to adjust the sonic qualities is my basic rule
