Thanx for the info, after I posted the post, I finally figured it out. As for the dragons tooth, Mat Rags is the pointy head correlian. If you talk to him and show interest in krayt dragons, and be nice to him, he will give you a dragon's tooth. Use the tooth at the vendor on your left when you enter the city and you'll get a blaster.
