The error messages look like maxima is trying to evaluate the actual
string within double quotes!

Good question. Has anybody else used maxima with org babel on Windows?
I don't even have such a system to try...  

My guess would be that the "shell" command required to invoke maxima on
Windows needs to be significantly different than what we are using here
(which works on Linux).  Then again, I've never really used Windows
(beyond starting Word on somebody else's document on somebody else's
machine... ;-) so I don't have a clue what Windows expects...
