Head on over to the HTPC section, it is very helpful.
You obviously have 7MC running on a PC, so that is where the customization would take place. Then the Xbox 360 acting as an extender will replicate the look you have from 7MC.
I personally use MediaBrowser as an add-on customizable media player, this handles all my media, meta-data, information, etc. Then to customize the actual look of 7MC, themes, strips, etc... I use Media Center Studio.
Good luck.
