Do you plan on getting full BGP routes from your upstream?  If so, go 
with 1Gb of ram on the NPE G1.

I believe that IOS 12.4.25c is the latest version for the 7200VXR 
series.  It's stable, been running it for quite some time.  Depending on 
what you will be doing with this router, will depend on what feature set 
you'll want.  I typically use the Service Provider IOS with IPSEC, 3DES 
and Lawful Intercept.
