Here's the best, non jagged picture I could get. I smoothed out some of the jaggedness with these settings on the material tab:
texture resolution --"highest (256x256)"
texture settings--"use global settings"

Then, in the file tab next to the materials tab, I went under "extra attributes," and there was a "resolution" box with the number 256 in it. I changed the number to 1024 and this is what smoothed out the picture as much as it did.

Anyway, it's pretty good now and I'm set to get started.

Thanks for the help and the followup Keith. I appreciate the kindness.
