Full mesh core network capabilities

Greetings everyone,


I just started at a new company in which the previous network engineer left half way through completing a new core infrastructure design.  I'm kind of working off his base but made some changes.  My question is, ultilizing the following equipment and design, are there any glaring issues we might run into as far as the design we are looking at using the equipment available?

The four switches shown are 3750G running 12.2(25)SEE2. They do have the ip services ugprade.

the two firewalls are ASA 5510s with the addtional 4ge ssm expansion card, both running the Security Plus Licenses.

The basic idea is to have full failover/redundancy.  The COLO has a similar setup except only 1 ASA and 1 Core switch with a 10Mbps WAN pipe that advirtises as a tertiary BGP link.

Our main concern is, do the switches and ASA have the technical capability (using a combination of routing, failover, hsrp, etc) to support this setup so that if any link/links/devices should fail, traffic will continue to flow automatically through whatever path is still available?  

thanks in advance
