Good News! I finally got it working. Using tcpdump I tried a couple of different configs till I got F5 to acutally route traffic to the VMs in the pool (which is were I erroneously thought I was at when I started this conversation). The config that solved this part was setting up a route for the 158 subnet that routed to the default gateway on the 92 subnet (which is also the external VLAN). Then I set the SNAT Pool for the Virtual Server to Auto Map and it all started working. Thank You once again to everyone that responded and gave me insight into my problem and debugging suggestions.
