FrankenMauser hit it on the head.
I would toss a few used dryer softener sheets into the tumbler (cut them in to 2x6 squares) to help control the dust.
As far as the staining goes, I have not noticed any difference in brass life. Of course you are going to inspect them to make sure they are not pitted or cracked.
I have some brass that is very discolored (I used them for black powder). Just clean, dry, tumble, reload, shoot and repeat.
Good job on scoring free brass.
