Yes, you can definitely get a callous on your tongue from a rough back tooth. You can go to the dentist to have this taken care of and sawed down.
No, it ends before the end of the mouth.
tongue
The tongue is effectively one big muscle but it has got different sets of firbres which are often seen as separate muscles; the two (Superior and Inferior) Longitudonal fibres, the Transverse fibres and the Vertical fibres. The Genioglossus is never agreed upon whether it is part of the tongue or not but it sits directly underneath it at any rate. Anything (muslces, vessels or nerves) that are related to the tongue have the term Glossus in some form in their name. This is the old latin name for the tongue but nowadays you will not often hear it as just calling it the tonue is far more prevelant.

The tongue extends back to the base of the mouth, where it is attached to the hyoid bone and the mandible (jawbone). It also reaches towards the epiglottis, which helps with swallowing and preventing food from entering the windpipe.
