Also some of the tutorials on this site might help you along the way, I think the best way to learn modeling would be to start simple with less detailed things like objects and interior scenes. If you have a look in the free section there's a few tutorials that might come in handy to get some practical techniques down, like the glass jug, intro to game texturing, dynamic object placement and the interior scene

For complete modeling projects in Maya we have more video training than any other site, they're not free but most of them cover modeling, UV layout and texturing. A few of them also cover the complete production pipeline with lighting, rigging and animation. For character modeling you're best off to start with less detailed things like low poly and cartoon characters and then move onto more detailed things. You can find the modeling library here
