Welcome aboard! I also started out tent camping before getting my TT.
As for tips I would suggest figuring out what you really need to buy now and what can you get later on. Once I figured out my camping style I ended returning a lot of stuff.
Keeping things simple has works best for me. For an example I have a small folding table that I often will use. Instead of carrying another table cloth I just use my beach towel as a cover. That same beach towel comes in handy as a pad for the little step stool that I sometimes use as a foot rest.
