The process is the same regardless of the emulator or frontend you're using. If you have the bezel files in the correct location all you have to do is set bezels enabled on the Settings->Bezel tab in RLUI. If you set it for the Global system it will enable bezels for all systems that have bezel files.
There are no other RL forums and there isn't usually a bunch of people here troubleshooting, just a few. That being said, in most cases just poking around RLUI can yield what you want or using the wiki or searching the forum.
