Campus failover question and hsrp between 6509 and 3550

The are quite a few questions here, I know.

Hi. I have a campus, WAN DR failover project an am faced with the following problem.
I need to provide failover WAN services for the campus if teh computer room fails but also need
to redirect several networks(vlans) that currently are configured at my core to a DR site over the WAN.

Computer room in building A is conencted to campus IDF in building B. Building A has a cisco 6509 running native IOS and RPR+ and building B has three 3550's with EMI(IPservices). These are currently connected via dual dot1q trunks and spanning tree. All L3 is however done at the 6509 at this point, the 3550's are acting as l2 devices.
Wan routers exist at both buildings and they are using hsrp for failover.

In the event thatbuilding A is severed from teh network I need to provide L3 routing at building B
for the vlans local to B (client vlans) but also route the building A (server vlans) to the WAN router
out to the DR site.

Can I run hsrp between the 6509 and 3550's but only provide addresses for the building B vlans?

Does RPR+ on the 6509 interfere with this?
Can I set the hsrp priority so that the 6509 is primary unless something comes about with it?
How can I force the 3550's to route building A vlan traffic to the WAN router in case of a failure?

Thanks, Al
