Hey! Welcome to the Full frame world and congrats on picking up a 5D MKII at such an awesome price.
I have one myself as well as a MKIII and a 7D. The 7D has been my main video camera because it killed the MKII but I am now starting to use the MKIII more often.

Love to see some photos when you get confident on all the settings etc, check the firmware when you get it because Canon released some great firmware updates for the MKII.
