Now - before you buying a banjo mute from someone else, you need to consider buying one of Rick Fielding's mutes. These things make your banjo whisper and give it a really wonderful dreamy sound. This is a great tool!

Re; Setup. I haven't touched my neck/action at all. I like it fine where it is - but I have tightened up the head a bit, and like to keep it fairly snug. And I've kept my eye on the bridge placement. The 'macro' level bridge placement is easy enough to sort out (I occasionally remove all strings at once to change them and give the metal work a good cloth scrubbing) but I've always used the harmonic vs the natural pitch method to refine the placement of the bridge. Is this how everyone does it?
