For performance numbers, search cisco.com for "routerperformance.pdf" - it's
a very nice document (and even regularily updated!) that lists all the
routers and their worst-case performance with 64 byte packets (but
without ACLs and other features).

The PDF lists the NPE-G1 as "500 mbit/s", so it should easily handle 
155 Mbit/s of an OC-3.  Just make sure to put in max DRAM (1G), otherwise
full BGP will be painful.

As for software recommendation - hard to say, since the 12.2S* situation
is less than clear.  For a "plain IP+IPv6 router with BGP", I think I'd
go for 12.3(latest) or 12.4(latest).  Avoid any IOS with a capital letter
in it (12.4T, 12.2SR, ...) unless you need the features.
