Firstly, welcome. It would be helpful to know where you are. What country? It is the wrong time to be re potting now, spring is the time for re potting. I would do the styling in the pot it is in before moving anyway. It is a good looking piece of material, and may make a good bonsai with a lot of work. It is difficult to say what to do without getting hands on, so it is down to you. You can do some of the work now, but I would not do all at the same time, I would spread it out.
Geoff.
