Knowing everything going in ain't gonna happen, mostly because noone knows everything. At 13 no one /really/ expects you to know what you're doing anyway, so just be an assistant and try to learn as you go (presuming your neighbor knows what he/she is doing). As stated, howstuffworks.com is an okay place to start, if a little annoying to navigate. Something like a "Cars for Dummies" would be alright, if it exists. If all else fails, take lots of pictures as you're disassembling things so you know where it all goes when you put it back together. And keep your parts organized and ideally labeled. Letter- or number-coding the ends of electrical and other connections is an excellent habit to have.
Also, try to ask specific questions. You're much more likely to get a useful answer that way.
