You really do not have much room to play with in terms of redundancy, you
only have a single router and a single T3 link. The ideal solution would
involve getting a second router and a T3 or even a T1 link, and connect
this router to the switches just like the first router; then use HSRP
appropriately.
If getting another WAN link is not feasible, you can get a second cheap
router on ebay and connect it directly to the first router and make them
HSRP Peers, but the router connected to the WAN link will always be the
active peer; this way you can provide some kind of layer 3 redundancy. If
you are you using just layer 2 switches, then you only need a single
connection from each router to each switch.
Hope this helps
