To increase performances, I will build some Etherchannel between the 6509 and Servers, edge Switches, etc.
To increase availability, I am considering to spread the EtherChannel (two links each), across the two Switch: one link on Switch "A" and one link on Switch "B", using LACP and one of the load-balancing method.
As Toshi mentions, you would need to run VSS on your 6500 pair. (I also understand there are some "quirks", at the moment, in building Etherchannel across VSS pairs.)
What you might consider, building 2nd connection to 2nd 6500 for redundancy using STP (or something like Flexlink?). And/or building Ethernchannel to same 6500 across line cards. If you do both, you might also not build the backup path with Etherchannel since it would only come into play with a failure of the other 6500 chassis.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
