thetucks - No no, you're fine. A camera, preferably digital, is a nice thing to have along the way so you can document what goes where & in what order. Its also good for what you might find once you start digging thru the motor, such as scarred cyl. walls, broken/missing parts, etc. The pictures come in handy when you put things back together especially when things sit with some time in between. Get a box of sandwich zip-lock bags, a Sharpie marker and a roll of masking tape so you can put pieces in the bags and label them for later. Most importantly, and I can't stress this enough, if you don't know ask for help. If you're not sure, just say so. Everyone here is willing to help and share whatever tips & tricks they have come upon along the way.
Remember, this is supposed to be fun. Good luck!
