Remove all upper oil pan bolts. all 12mm exept the 2 small 10mm nuts behind the dust cover on the upper pan where it meets the tranny. behind that are two nuts that need to be removed that are attatched to the rear main seal housing. If you dont remove these and try to remove the pan you will most likely break the housing and your in for more work than what you started. Make sure and double check you have all the bolts out. there are about 6 total bolts that are behind that baffle you just removed on the inside of the motor. If the pan doesnt come off fairly easy you probably missed one. The pry point is at the front most corner near the tranny on the block, you will see the indentation where a flat tip can easily lodge under the upper pan.
