New TM Owner

Just purchased a 97 3023.  This is my first TM as well as my first trailer period.  I am new to camping and have a couple of questions.  Does anyone have a list of "stuff" I need to start collecting.  Ex: propane camp stove, chemicals for toilet, etc.  Secondly, I want to get a generator.  Anyone have any suggestions?  How quiet does it have to be?  How big to power the air conditioning?  Any help would be greatly appreciated.
