I made sure to buy Timken bearings. The same part numbers that came out for each bearing. If that makes a difference and helps with the alignment of everything?

Before i put the axle in i am wondering if i should do the oil pan gasket and rear main seal before putting everything back together. My question is that i plan on swapping in a 4x4 aw4 in at a later point. Will removing the trans later mess up the rear main seal if i plan to do it now.? I dont want to do the work now then mess it up later when i swap the trans. Any input?

Finally got around to checking the wear pattern on my gears. I didn’t have a torque wrench big enough to be able to do 220 ft pounds for the pinion nut so i just hit it with my Milwaukee impact gun. Idk if that will make a big difference or not. The coast pattern? Underneath looks to be to far back as you can see. How would that be adjusted?

You may be able to run with that. It may be noisy at first, but it should settle down.
Also, you don't want to be tightening and removing the pinion nut too many times, at the threads will get messed up and can then damaged the threads on the pinion. If you have to do it, don't use the impact gun. Just use your hand wrench to make it tight, and be careful not to damage the threads.
Here is a chart that shows you the patterns and how to adjust them:

i don’t have the right tools to check backlash and everything, so i was just doing trial and error until i get it right. Since i just replaced bearings on the used gears i put back all the shims that came from the original stock gear setup. The pinion has 3 shims in it now with this wear pattern.

You need to get I dial indicator and mangnetic base so you can check your backlash, the one from Harbor Freight works fine.
