You can also get the DRGs, and FSA color photos as a WMS: http://deli.dnr.state.mn.us/services.html
And all wrapped up with a nice mapServer interface...
(Not that I can't see and appreciate the value of just dropping $1600 as a group fee to have DRGs for the whole US) I can even appreciate the value in paying to 'set the data free' from a stick it to the Man perspective... Power to the Pixels!!

A lot. Ask me how I know :)

Unclear.

Yup. Most of the other 40 do.

Oh, those 10 don't have any at all.

They're georeferenced. You can script the renames. Again, ask me how I
know... You then only need to handle weird cases (like, along coasts where
they have abnormally sized maps) by hand.
