I can lift the door slightly but something I noticed was that I can lock the door then close it and it latches but still won't lock.Otherwise it has trouble even latching. Should I just replace pins and actuator/lock mechanism?

And this: https://dodgeforum.com/forum/2nd-gen...-sounds-2.html

It really just does the noise if its been sitting and usually goes away after warmup and a drive but I'll still have it looked at.

And I also had the common oil pressure drop and was told to replace the pressure sensor and pump but is there any specific brand for either I should look into?

 

Door latch: Replace the pins and bushings, and see what ya get.

Oil Pressure: Replace the sensor. See what happens. (or, test with a mechanical gauge, and see what happens. )
