Walls and Ceilings - Drywall Tools

I am planning on re-doing the walls in my bedroom. I have a buddy and his dad going to help me out because I obviously dont know how to do it yet. I am planning on doing most all rooms in my new house so I need to plan for that as well. My question is I need a list of all tools and supplies to start buying. Any brand names for quilty supplies would also help. Also in my room, one wall is a outside wall as also is the celing. Not sure if I need anything special for those. Also should I insulate the internal walls as I know I will need to do the external ones? Also if there are any links that would tell me what I need that would help to.

Thanks A Lot!
