To the OP - You should check and see if there is co-op bike shop in your area. Many major cities and college towns have them. You pay a membership fee and/or volunteer your time in exchange for use of the shop which will include all the tools to work on your bike. Often these places have maintenance classes that cover the different aspect of working on your bike. Some commercial bike shops have these as well, but the advantage of the co-op model is you can take your bike there and do the work when the class is over.

Taking a wheel building class is how I got into it. I did my share of internet research and question asking, but I ultimately decided I wanted the hands-on experience. If I'm counting correctly I just built my 13th wheel last night.
