+1 for iZotope's RX.
I use RX4 Advanced exclusively for editing - things like string squeaks, and various clicks and pops.
iZotope just keep making it better and better...
I have SoundForge 11 Pro and still use it, though no power user stuff here and never used it for CD burning.
(CD Architect was my primary "Red" burner for a long time, but Sony let that one slip away, so I moved to HOFA.)
Both RX and SoundForge are set up here to launch from Sonar's Utilities menu, which is a great way to edit from within Sonar...When it works, it's downright magical.
(Lately it's been working great, but RX and Sonar have been known to fight over the main audio driver...)
Goldwave was an early favorite, but I lost track of that one. The feature set for the price was outstanding.
