For leveling the stand: If you have a large base plate on the floor or if the legs are large pieces of wood you might consider the following (sorry if I'm way off base here!): In the big hardware stores you can walk through the section where they have vinyl floor tiles and other flooring type things -- I found some long thin vinyl strips where you pull off the backing and they have glue - they are meant for fake floors or baseplates along walls or something (these were fake wood on the showing side).. anyway, the important part was that they are quite thin and the vinyl doesn't compress much and they cut with scissors or a box knife. So you leave the paper on and cut them to fit the -bottom- of the left feet of your stand or the bottom of the left side or whatever. You can measure their thickness and plan how many stacked will offset your imbalance. Finally you just pull the paper off, stick them upside down to the bottom of your stand and then use your level to check the stand after you've turned it back over.
Anyway, just a thought in case it might happen to be any help,
