I haven't verified all your listed features but a 3925 router would probably meet most of your them.
Should provide performance of at least 700kpps
I agree with Joseph. This sounds like a 3925
Should have at least 3 Gig interfaces (at least 1 SFP Port)
Should have at least 2 FE interface
The 3925 already comes with default three 1 Gbps interface (1 SFP dual-personality port). So you need to purchase additional module(s) for the fastethernet ports. You can either have a routed or a switchport.
