This should help, this video is for a Commander with the 3.7L V-6 4x4;
The fact that this Commander has 4WD, has no bearing on the part of the job that you're interested in, which is how to get the oil pan off.
How to do a oil pan gasket on a ( 2006-2010 Jeep Commander 4x4 ) - YouTube
He also had some pretty good tips, about letting the RTV harden somewhat, before you try & put the gasket back on.
Pretty good video.
