I had a go with SU Animate a long time ago and I didn't get very far - would you recommend it for the kind of object animation I am describing?
I believe SUA has a free trial so it can't hurt to give it a try. I've not used it a lot, but found it easier to set up than Proper Animation. SUA recently released a pretty major update that now includes key frames. I've toyed with Keyframe, but haven't used it for anything so I don't know how it compares.
