Files are generally mkv. Sometimes avi or mp4. I have never tried it on an iso, personally. For rips, I generally want minimal, no menus, extras etc, just the film.

The biggest plex issue for me is that I havent found a way to get Plex to decode the AC3/DTS track to PCM for transmitting over HDMI so the HD621 can upsample.

I actually just have the Mac Mini under the TV, it's pretty small. Not Apple TV small but small enough, and its very quiet.

With an Apple remote, you hit the "Menu" button and Plex just launches. I have to manually set the TV input and then use the Meridian MSR for everything else. I can't really be bothered with Universal remotes. Years ago, I had a Philips Pronto, which was a really nice little remote. However, I was spending way too much time fiddling with screens etc. I actually like using the MSR so I've stuck with it.
