First of all, I can't believe the Honda chain lube instructions say to use brake/contact cleaner on your chain!
These cleaners are very caustic, and should only be used on metal parts. Unless Honda's brand-name cleaner is some different kind of "friendly" formula, the stuff will dry out and ruin the O-rings in your chain, as well as dissolving all the grease inside.
For your chain, you're better off using kerosene or WD-40 (which is the same thing) to clean it.
With the bike on the rear stand, spin the rear tire slowly (it helps to have an assistant do this) and spray lube onto the inside portion of the chain. The easiest place to spray is the portion running underneath the swingarm, spraying downward. Spray into the area between the links, where the O-rings are. After a nice coating, you can wipe down the outer links with a rag, to help keep them from attracting dirt.
There are many other helpful hints in the "How Do I" forum. Look through there for chain-related topics.
On your work stands, no, the surface doesn't have to be perfectly level, but if you have to do it on an incline of any kind, make sure the bike is pointing UPHILL!
Pit Bulls have pretty good sized wheels, so you can probably use them on hard packed dirt or fine gravel, if it's not too deep...
A fool and his money are soon partying.
