If you are going to have local uplinks in your other locations (and it is not just a hub-and-spoke design with no need for internet redundancy), then I would run the same ASN throughout, use BGP Confederations (maybe not, depending on the number of uplinks, routers and your client's transport requirements). Stick to using OSPF (or another IGP) for the local lans in each location.
If it is just a central-office, branch-office kind of thing, with no external uplink redundancy, you might be able to get away with OSPF for the entire topology. It really depends on the specifics which I don't have. :) Can be done many different ways as well..
