Oil changes an it looks like every service record since new.... Tire rotations..... Someone's parents owned it since new an gave it to the daughter an a few months later she opts for a 4 cylinder something instead..... And I show up with a buncha cash..... Anyways.... What's the thoughts on switching to synthetics all over. Diff's and tranny an engine. Is there one I should avoid? Is there one that is magically better than all the rest?

Your call. You can go with synth blends, or you can go with pure synth.
Even though it has good service records, you might want to think about a Seafoam treatment on the engine before you cut over.
Watch out on the differentials and transfer case. The factory fluids last quite a while, and it is easier to match them up with the friction modifiers to get best operation.
Keep an eye out for the steering stabilizer, although if you start getting death wobble you really should fix the suspension parts before you replace the stabilizer.
If you have a trusted jeep specialist or dealer, take it in and ask them how much it would take to cherry it out... and the urgency. Cost ya about a hundred, which is cheap sleep insurance.
