Sorry, forgot to answer the second part of this...

Yes, you can do active/standby.  You can create a primary server farm 
with one IP and then a backup server farm with the other IP.  When 
creating your virtual server address you can specify the primary and 
backup server farms.

But this assumes your SLB works correctly with L3 hops.  COnnections 
coming in via L3 hops will be load balanced, anything directly layer2 
adjacent on the same subnet will not be load balanced.
