why do you require HSRP in 3750 between the switch and the PIX ? on the 3750's you just need to give the default gateway to the Primary PIX. Once the Primary goes down, the secondary automatically takes the Primary's IP.
why do you require the 2950 switch? it is again a SPOF (single point of failure). instead, you can connect the primary 3750 to PIX 1 and secondary 3750 to PIX 2.
