You can have as many channel logos or favorite channels as you have channels. This is something you'd have to either program in yourself or have programmed. X10 can be controlled via an IR543 IR-to-X10 controller. If you're familiar with Harmonys, you should know that the MX-3000 requires some serious programming to reach its full potential. It's not a Q&A-based setup like the Harmonys, but it allows for much more flexibility in programming.
