Since option 2 or 3 are not viable because I don't have complete control of
the remote network. Option 1 would be the most viable one.

What kind of routes would I need to make in order for this to work?

|With the configuration that you're describing you have two, 
|make that 3 options.  1. set a static route on each 
|workstation.  2. configure your current internet gateway to 
|route through the vpn to get to the remote machines.  3. 
|change your vpn machine to be your default router, set it up 
|to route through the existing gateway for all normal traffice, 
|and to use the vpn for the machines on the other side of the vpn.
