Please donwload the latest version, which is DrScheme 103.  If your
institution is still using 101, please ask them to upgrade -- 101 is a 
few years out of date!

Upgrade.

None at this point, unfortunately -- that hasn't been an area on which 
we've focused much.

I'm not sure what your question is.  DrScheme has several extensions
to the standard Scheme language, which are necessary for writing many
of the programs one might want to write (eg, the card games).
