I think Plex is the way to go as well.
Other than that, another approach would be a remote desktop app for the iPad. I have iTeleport on mine, and it allows me to control the Mac mini in my living room as if I was sitting in front of it with a mouse and keyboard.
If you really just want to keep things as simple as possible, you could try using Front Row on your Mac mini. It should be able to access music from your office Mac using Home Sharing (like you have set up already). Front Row is already installed on your Mac mini, and is controllable with a physical remote control.
