Joel, I don't know of any sites to recommend. I know I saw a New Yankee Woodshop episode of Norm building a shed that might be of use (Rennie, Do you know the episode?). Other than that, you might go to the local library and look through the plan books they have. I know my library has a bunch of books for such a project.
Good Luck, and show us some project pics.
