Yes, it's that simple. You don't need MP-BGP or MPLS for VRF lite to work.
You need MP-BGP only if you want to leak routes between VRFs (as the leaking
is based on route targets and has to go through MP-BGP). Just make sure CEF
is enabled (which is not an issue on a 6500).

(Warning: self-promotion in the next sentence) You'll find very good
coverage of the VRF lite topic in the "MPLS VPN Architectures, Volume II".

Best regards
Ivan
