Well it sounds like you have Recall down. Make sure you are keeping a Dream Journal just in case. After that what you should do is pick up a technique you think you want to get good with VILD, WILD, MILD, etc. After that once you are in the dream what you want to do is get dream stabilization down I.E. rubbing your hands, focusing on objects, etc. to make sure your dream doesn't go anywhere. After that you can do whatever you want.
