To be honest: It's a huge pain in the a$$ to remove the oil pan with the engine still in the car. Here's what I can tell you, though, from the one time I did it...
1. safely raise car
2. drain oil
3. unplug and remove oil level sensor (I didn't and broke mine)
4. remove nuts on motor mount (passenger side)
5. safely support passenger side of engine
6. loosen all 4 sub-frame bolts
7. place a jack under the passenger side of sub-frame
8. remove passenger side sub-frame bolts
9. slowly lower jack until all bolts are accessible on oil pan.
10. unbolt oil pan.
11. slowly work it off and wiggle it around to remove it. Be aware of the pick-up tube while you are pulling. You may have to lower the sub-frame even more to get the pan out.
