A T1 is 1.536mbs (MB/s != mbs). I would suggest that you should monitor the traffic utlization over the network and see whether dual-T1s are reasonable for your applications. No one can recommend one solution or another for your use without looking at you traffic. Since all the servers and clients seem to be running right now, just watch it. In fact, I'm astonished that anyone would put a network in without quantifing the throughput requirements of each site and the users at the site.
