You will want to start with a frame, and work from there. If you don't know what size of frame you need go to a bike shop and get fitted. Are you building the bike for the thrill of building something yourself, or in hopes of building the bike for cheaper than an already manufactured bike? Depending on parts you will find the premanufactured bikes run cheaper than building your own (unless you find a parts wholesaler).
I'd say pick up a thorough bike repair manual and look at the annual maintenance section where it goes through stripping the bike down and reassembling it. For me, a bike repair manual with good photos helps the most.
