Typically on an 8" you would probably use a drop bracket for the radius arms. I personally think the OUO adjustable radius arms are nice since they will get your caster back in check and it is adjustable for different lift heights. Most of the kits don't come with enough caster built in them.
Stock driveshaft will actually work fine. You can use shims or you can get a kit OUO makes for carrier bearing that can pretty much get your driveline angles in check.

The full ouo carrier drop won't work on a new truck, have to use the mini. 8 inch is getting to that limit where thjngs get sketchy. It's true with a 4 link or adjustable arms you can keep the castor in check but at the expense of pinion angle. There's a point where it gets where the truck will be a pavement queen unless you get a high angle front shaft or an index ring. Rear driveshaft should be ok for length but it's always best to check. My best advice is if you want a driver that will work with no custom parts and little trouble, stay under 6 inch or less.

Definitely the front shaft is not happy. The length works but the angle isn't great. It will work but definitely nothing that is going to work very well if you do any offroading. I would probably go with the front driveline work over clocking the t-case.
If you are like anybody else once you get to 8" then all of a sudden 10" looks better....and so forth....LOL $$$

Any time you alter the suspension you will have to get an alignment which in that will check castor angle. Whether you use drop brackets, 4 link, aftermarket radius arms or what not castor angle may need adjusted. With drop brackets it will be just like setting everything from the factory, use the bushings at the ball joint. Anything else aftermarket that's adjustable this is where you can get in trouble. Sure you can set your castor with the suspension adjustment but at the expense of your pinion angle. Set the pinion angle first and then use the bushings at the ball joint you do the alignment. There's only so far you can go with the bushings before you start using the suspension you get you castor, which if you are that far you have exceeded the limit of the lift kit you are using. That's when things start getting rather expensive.
