Good stuff Jim,

My only suggestion would be to consider the use of screw jacks (also known as barn jacks) in place of hydraulic. It's much easier to gauge how much force you're applying to the frame (more weight means harder to turn jack screw) and they're not going to come back down until you're ready. I also like to use cribbing stacks instead of posts when its practical since they don't kick out.

Cleary a matter of personal choice on my part. Trust me it comes from learning the "hard" way.

Keep the good info coming!
