I got stuck in a creek with the bottom half of my engine under wate and had to wait 2 hours for my friend to pull me out. Is there anything that i need to do to get everythin running again. such as repack bearings and such.

give the engine bay a good cleaning, make sure nothing got water in it, that's about it... i had my jeep stuck for 3.5 hours like that and the driver side floor filled up too! xD i drove her 25min home with no problems!

I dunk mine ALLLLL the time
you should be fine, just check
all your fluids for water... including
your diffs.

Change diff fluid just to be safe I'd say.

Dif fluid change up is cheap and excellent insurance against future problems. We see quite a few start problems with summerged, not the water, it's the muck that gets into them. If your stuck was clean then less chance of problem. If really soupy, then watch the starter. A few buds have also done in the clutch. Design of that one has my head shaking. It's a jeep, the clutch shouldn't lead to fail because of water crossing. I'll stick with the AW4 thankyou. Other than getting a good undercarriage hose job and pump those universals full of grease to force out any water, you should be good to go.
