Yes, you should try a few modelling programs and see what you like. Programs like milshape cost money but if you go to the website, you can download a trial version. Some free modellers are DeleD, Blender, and Doga. Those all can be downloaded from their websites and have plenty of tutorials. If you want to try some of those modellers but cant find the website, just say so and i will post the links.

edit:
Oh yes, and you can also find some tutorials for different modellers at 3dcafe.
When it comes to programing, I'm on fire!
