Hi Barry,
I am not exactly sure what you are asking? Are you asking for a guidline on how to have the F5 to offload the certificates.
If so then at a high level here are the basic steps
1) Create a SSL Certificate and get it signed
2) Create a Client SSL Profile making sure you reference the signed SSL Cert
3) You then create a pool which contains your server on HTTP
4) You then create a VIP on 443 that associates with the Client SSL profile and the HTTP pool you created.
Of course I am not exactly sure how you website works, but hopefully this can be a guide
