1. Can I enable iBGP between the PE's in a full mesh to allow traffic between the PE's without going to the core's. Or does this break the Route Reflector model?
If I have understood your design correctly then don't use next-hop-self on the RR's. Ideally you'd have out of band RRs so you don't need NHS but I can see that you're are both RRs and PEs so NHS is required. If you enabled iBGP sessions between all your PEs you have defeated the point of RRs :) I don't know your setup in detail but is there something you can do on your RRs to allow you to remove NHS? eBGP routes will have NHS by default so you just need to check the impact on iBGP routes, maybe you can remove NHS at the expense of redistributing a couple of connected routes.
