Can you somehow find the coords of a certain vertex after it has been rotated, scaled, or translated?

Yes, use Feeback mode. The Red book has a demo on it.

Or multiply the vertex position in object space with the modelview matrix after your translations and rotations http://www.opengl.org/discussion_boards/ubb/smile.gif.
Then youŽll get the vertex position in eye space.
