Here is a site devoted to those who love to hot-rod tele's. The Fender Telecaster Lover's Modification Site contains profiles of individuals who modify telecasters, and the guitars that they have completed. A great source of information and ideas when considering a hot-rod project. I used this site during my own project.
There is also a discussion forum, along with a well-anotated links page, linking to companies that make replacement parts and modified parts for Fender Tele's. They are quite honest with their ratings as well. They also have a tips and tricks page that has some interesting and useful info for those embarking on a project. If you have ever found yourself hovering over your Telecaster with a soldering iron, you need to check this site out.
