600Mb is going to be really pushing it. I doubt it will be able to handle that kind of throughput.
Even with G2 I would think you would be pushing it.

We won't be doing any QOS or IPv6 on it but it does take a full BGP table. I just need it to last another year or two out of it if possible. I believe this platform goes End of Support in Spring 2016.

If you or a customer have these deployed, how much bandwidth have you seen them handle? This will be handling dorm traffic at a college so it's mostly download.

Full routing and ACL 100+ entries? I would ditch the 7200+NPE-G1 or upgrade to an NPE-G2..
