I agree, hit up the beginner runs and take it slow. Start out just coasting over small jumps without jumping, work your way up to a couple inches of jump etc. Maybe hit those small jibs that are level with the surface. Baby steps. Watch some youtube vids to get the basic ideas of what you should be doing. Some of them are pretty good. Im in a similar position and am pretty happy with my progression. Just be ready to start falling all over again.
EDIT: And a helmet is a pretty good idea if you dont already have one.
