hm, well, cats are naturally good at using their paws for things from what I found, so a lot of what I teach him centers on that. He knows high five, shake, wave hello/goodbye, and will either target with nose ("target") or paw ("touch") if I point to something. He also knows down, weave (around legs), on (an obstacle/furniture), off (same), stand (on hind legs), spin (both directions), roll over (both directions) and probably other stuff I'm forgetting since I have been using all of my training energy on my pup for a few months now. Actually when I train my dog he tends to be right there too, haha, especially if I'm using the clicker. No matter where in the house he is, he comes running fast if he hears the click.
Can't help too much with the reward stuff, all 3 of my cats would cut you for one piece of kibble. It may be because I meal feed them all and not as much as they'd like, so you could work on building food motivation by hand-feeding kibble as supplement or full meal rather than bowl feeding or leaving kibble out ad lib.
