I don't know jack about wands, other than they're pretty and a tool.
You can cast a spell without any tools to aid you. It's all about the energy you project. Some people use tools as a way to borrow energy, candles for example...you are/can borrow the energy from the flame, as well as send some of your energy into the candle to help it aid your bidding.
It isn't necessary for any of this if you don't want, but you do need a decent grasp of how to use your energy and the energy around you at all times. Some people can perform a spell with simply thinking of their desire.
A spell book is always a work in progress. You don't have spells yet, but that doesn't mean you can't put in the information you know about magick now. If you are into color meanings, make a page describing the color attributes. If you have found a good method of meditation, put it in writing.
A spell book is not just a book of spells, it's a book of your growth in using magick.
Oh, and nothing stupid in your questions at all. =)
