Hoo boy, man, that's a big can o'worms.
Are you a woodworker already? If so, you're already familiar with gouges, chisels, planes, scrapers, yada yada yada. If not, then you should start perusing tool catalogues and using tools. Also, if you're at that early stage of learning to make things out of wood, maybe you should think about going to school, joining a class or a club or something, and try your hand at making a few things. I know it drives Bob Branstetter nuts when I say things like this, but there's a surprising amount of similarity between building a fine piece of, say, furniture and building a bass. The similarity lies in having an intimate, real, experience-borne feel for the material in your hands, which is wood. Also, there's a ton of stuff to know about tools: using them, maintaining them, not cutting off bass-playing fingers, etc.
There are several major vendors of good woodworking tools on the net with great catalogues. Check out Lee Valley, with whom I'm quite familiar as they're a Canadian firm and I'm, well, Canadian. Been dealing with them for 25 years and have learned lots about tools just by keeping the catalogue in the crapper. Great reading.
There are some truly specialized luthier's tools; you'll learn about them as you need to know about them (endpin reamers, finger planes, etc.)
There are lots of excellent woodworkers where in their shop you'll see whole walls full of carving tools and chisels. Watch them work for a while and you'll observe them doing two thirds of the work with maybe 2 chisels that they happen to like a lot. A "luthier's knife"? In the hands of an experienced person, a pocket knife will do the job, maybe even a butter knife if you could get an edge on it.
Here's the thing about tools: don't run out and buy a whole shop full of tools that you think you may need at some point in the future. Buy excellent quality tools (the best you can afford; in the long run they really are the cheapest tools you can buy), buy them when you need them for a specific job, and learn how to use them. Hand tools especially take practice. You'll have to wreck some stock to get good, that's the way it works.
Finally, I'm betting Jeff's straight edge is a Starrett.
