A VRF is a separate virtual routing instance within a router, with its own 
routing and forwarding tables.  Unless there is some level of traffic 
separation that you need, setting up VRFs or MPLS probably won't do you 
much good.  Without knowing more about your architecture and needs, this 
is just a general statement.

I'm not sure what you mean by "the fast switching method of MPLS", but 
from what you've described about your network, I'd think that enabling CEF 
on those four routers should help them run more efficiently, if it isn't 
running already.  Fast switching and MPLS are two completely separate
