I think you could just use Animal legs or Insect legs from the robotics section as a base for calculating stats, the same goes for the arms and the tail could be a modified tentacle.

Of course as you're just thinking about these things, you could always take what you like and tweak it. If you're using these things in-game, consult your friends and GM on how to do these things without affecting game balance too much.

You should really try to come up with some way to do it by yourself and maybe get a solution that works for you. It's not that we don't enjoy offering suggestions to your questions, but for me at least, the challenge in roleplaying is thinking things up and then trying to see if I really can make it work in the game I use.
