Just about any book on the subject will be adequate to get the basics. There's also nearly nothing on a bicycle you can screw up in a way that you can't in-screw it up by turning the screw in the other direction (exception: wheel trueing, but even that you have to blow pretty bad to taco a rim). If you get into rebuilding mountain bike suspension, this doesn't apply, but that shouldn't be your first project anyway. Oh yeah, and hydraulic brakes probably also wouldn't be a great first project. Get a book and start experimenting. Plan on re-doing some work. Maybe find a way to hold the bike without investing in a work stand if you're over thirty. I've done a lot of work on the side of the road while bike touring, but that doesn't hold much appeal these days if I have another choice. ETA: get a tube of bike grease from Park and a bottle of chain lube (Tri-Flow is fine, and so is everything else). Those'll cover your lubricant needs for years.
