Should be able to, especially as you are using WGIC. However, you need NAT if you are using WinGate's bandwidth control feature.

Yes, you can. You can either specify it on every client PC (By running the WG Client configuration and setting the mode you want for that application) or, if you have an Enterprise license, by setting the applications in your WRP Centralised Configuration. (One point of config then, on the WinGate Server itself)

No, in fact, WinGate will stop the client if it is detected on the same machine, I believe. If you need that machine to go through WinGate itself, the best option is to proxy the appropriate applications through localhost.
