Sup2/MSFC2/PFC2 (it's all one big card) will do what you need.  AFAIK, 
Sup32 is featurewise a Sup720-3b, without the extra bus/bandwidth 
capacity.  The Sup2 gives you 2 GBIC interfaces.  Add additional cards for 
the interfaces you need.

512MB (make sure you get that on both the supervisor and MSFC2) is 
enough...at least for now.
