For recording my sets i use Audio Record Wizard....
its a damn pretty small program wich can record in every quality you want (for ex. 96/128/192/256 kbps).
This program even uses almost nothing from your system performance, AND! it can record straight to mp3
After that i edit my set with Acid Pro for pumping up the volume (never record your set with an to high volume ;)) and for adding some jingles.
Good luck!
