If you don't like then possibility of getting corrected, here isn't the best place to post with obviously inaccurate details. You asked a question, and gave inaccurate information vs the picture, all that was said, was to correct your information. For the bike, it's a GT i-drive, Timberline model 2001 GT Timberline iDrive - BikePedia, I had a l XCR version a few years ago, nice ride, but not that light, and can feel as though you are perched on the bike when riding.

For the crank, you may get away with just filing the broken teeth so they don't interfere with the shifting or anything else, if a complete crank is needed, you will need a square tapered one, preferably with 22/32/42 teeth, a Shimano Atlus M311 has this, or the Acera M391 (looks a lot nicer) comes with a 44t outer, your chain may work with this, buy you probably would need a new one to cope with the extra t on the outer.
