Drawmap is nice, but if I remember correctly it'll only parse DEMs into a contour maps.

If you're looking for topo type data you'll need to grab the DLG (Digital Line Graphic). I started a PHP script that parses them as topo maps but had to put it on hold a few months ago.It does display the maps now, pulling the data from postgres. I also created a script to get the DLGs into postgres. I'll pass either of these on if they'll help in any way.

DLG and DEM data can be found at the usgs.gov site. They can be ftp'd. I used a regexp to get only the _CO files.

Another good resource is freegis.org. Evelyn and D Stimits had a discussion about this and Evelyn mentioned a few other great links.
