Less is more. Because you're new your instructor will undoubtedly be making a lot of "adjustments" to your plane. For now you probably want all of the above and some stuff to do minor repairs.

But when you get better, get over it. It's really best to make any repair in your shop. It will be straighter, stronger, lighter and look better than field repairs. For now the most important thing is stick time and any trainer can take a beating and keep flying. So if it's a choice between flying and going home to repair, I say repair and fly.
