Ah, okay, MCR is Modaco Custom Rom and CM7 is Cyanogenmod 7. They're both very good custom ROMS based on Android 2.3.1 with some added features and/or other changes. MCR is closer to stock, imo, if that's something you're interested in.
In order to flash them to your device you need to be rooted(which you said you are), and be able to flash Clockwork Recovery via fastboot or ROM Manager. If you're not familiar with Clockwork recovery/ROM Manager, check out this thread before proceeding: http://forum.xda-developers.com/showthread.php?t=875875
