We're doing all of this on 7301's (very similar to 7200/NPE-G1) on IOS 
12.3(11)T2, plain IP feature set, very stable, no problems.  Note, 
however, that you will need a broadband feature license...

You can do MPLS and MPF in 12.4T, SP Services feature set.  As of now,
I'm not really counting on 12.4T (still young), but you might want to
give it a go if you really need PPPoE + MPLS (we've had it on one 
production router for a few months without a hitch, running PPPoE + BGP 
(2 full feeds) + OSPF + MPLS).

In your case, I'd go with 12.3T or 12.4 mainline and update to 12.4T
once it becomes more experienced and you start needing MPLS/MPF/IPv6 
(I'm not sure about IPv6 in 12.4T, though, I haven't used it).
