I can give you the torque specs later when I get my shop manual out.
Now, I actually know the answer to this as I rebuilt my engine in my car. To get the oil pan off, you will need to remove the cross member (2 bolts), the sway bar, and if the car has an automatic transmission the 2 transmission cooler lines from the radiator. Then all the bolts on the oil pan are 7/16 with the exception of the 4 bolts (2 respectively) on either side of the front and rear seal (which are 1/2). Once you have all of the bolts out, the oil pan will catch on the steering (I didn't want to mess with it), but you can EASILY pull the oil pan forward and over the steering. Then installation is the reverse of removal (except you swear in different places). lol
