Question on using two different gateways of last resort. Complex network @ 1 site.

Our final result to this is to have a group of computers on several different vlans use one internet connection, and another group of vlans use a the other internet connection.  
Our network has access to one t1 and one oc3 that is connected thru a router that we dont have control of, but have been given access to 1 port on a switch connected to that oc3 to use as a connection to the internet via a PIX515. The t1 is connected to a 2621, that has no acls or routes set on it, strictly a bridge from the t1 to the internal network via a PIX515.  We have approximately 24 vlans, routed thru a 3550g. We also have a 6506 that we use as a switch to connect several locations around a community via Fiber.  In order to see what Id like to accomplish, please look at the picure here http://kurzet.com/e-e_example/Drawing1.htm . this picture is the  way it is set up currently and it doesnt work. Now for the vlan and switch setup( as of current) explanation.
3550g-b is setup to use the PIX-2 as its gateway of last resort. 3550g-a is set up to use PIX 1 as its gateway of last resort. both set by using 0.0.0.0 0.0.0.0 (nnn.nnn.nnn.nnnaddress of inside port on pix)
For testing purposes, we have set up a vlan #69 (vlan 69) as our first vlan to be routed thru the pix 2 to get to the internet.  the vlans address is 192.168.69.1 We have a route on the 3550g-a that says "ip route 192.168.69.0 255.255.255.0 192.168.69.1" the PIX 2 addess is on a different vlan (181) so we are trying to get the traffic from vlan 69 to pass thru 3550g-a and be routed out PIX2.  While at the same time, the other traffic must be routed thru the 3550g-a to the PIX 1.
this is very difficult to explain... but that is it in a nutshell.

My feelingis that I need to not have the 3550g-a in between the 6506 and the 3550g-b. And that the gateway of last resort (GLR used in the picture) is conflicting with the 3550g-b's and sending it in the wrong direction...
Currently when I run a trace route from the 3550g-b to the ip address of the PIX 2 inside port, it stops at the vlan 69 address of 192.168.69.1 and can not continue further.

Any and all help will be appreciated in helping me figure out what the best way to to this is.

So with out having to paist several thousand lines of CLI from 6 different deivces, can some one explain the way this should be set up based on my needs
Thanks Experts!

I think that you need to implement Policy Based Routing (PBR)...see the following URL for more information.
