Yes, the identification of VPN at the edge PE is based on incoming interface.

It is assumed in the draft that the BGP/MPLS IP-VPN ingress
and egress PE routers have PCE capabilities. 
However we think it's possible to adapt the external PCE architectures.
It will require further study.

Yes, we need to consider it.
