Yep, looks like a low-end carbon steel frame with low-end components to me. The lugs are cool, and the bike looks to be in good shape.

+1 on the stem - lower it pronto (at least to the point where the horizontal line (with the "max" indication) is at or below the headset.

Double check the brake pads - it is likely that some new pads will be useful.

I'd give it a once over - check the condition and functionality of the cables, bearings, derailleur settings, etc, and it should be good to go.
