Sup720-3B supports MPLS/L3VPN in the way you described it.

As far as I know, much depends on the number of routes in the VRF's and
the overall number of Vlans on the router, but if you are just using it
moderately, you should be fine. 
Actually:
http://www.cisco.com/en/US/products/hw/switches/ps708/products_data_shee
t09186a0080159856.html mentions 700 VRFs with 350 routes/VRF.
