There is a lot you *can* do, but the realm of things that make sense is usually smaller :). That said, I'm not sure how TAF could be used for an instance. If your TNS connect descriptor requests INSTANCE_NAME, then I believe that will defeat TAF failover. That is, I don't think it makes sense to have FAILOVER=ON and INSTANCE_NAME=blah in the same descriptor. What are you trying to accomplish?
I like Jeremy Schneider's services whitepaper for a complete and thorough explanation of services, especially in a RAC context. It is on his website at http://www.ardentperf.com/pub/services-schneider07.pdf
