You may wish to consider online training sites like Lynda.com or Digital Tutors. They are relatively inexpensive on a per month subscription basis and you'll find all the video tutorials you'd need to learn how to model.

I'm from the old school and learned how to model from pouring over thousands of pages in books on modeling (along with trial and error) and I can tell you that I wished I would have started from these subscription sites instead but they didn't exist then. If a picture is worth a thousand words how much is a complete video course worth? :)
