Replacement of oilpan Excursion 7,3 diesel - NEED HELP AND TIPS !!

Hi
I am new to this forum, as my excursion is just been bought. My BIG problem is that i am living in Norway and we do not have expert help regarding excursion back home. It is a very rare car.
I have gotten hole in my oilpan, and have to replace it.
DO ANYONE KNOW ENOUGH ABOUT THIS TO HELP ME WITH TIPS ?
I have found out that the engine must out. What about the transmission ? Can it be leaved as is ?
What is the most common things to replace then when the engine is out except from the oilpan ?
The car has about 120000miles on it. Is it smart to maybe replace the rear main seal or other stuff ?

DO ANYONE HAVE SOME PICTURES OF A REPAIR LIKE THIS ?

I AM VERY THANKFULL IF SOMEONE COULD HAVE HELPED ME BY TIPS, PICTURES AND MAYBE IN WHICH ORDER TO START ?

BEST REGARDS THOR BJERKE, NORWAY.
