first you take them apart from the nuts (no pun intended) and then you fill them with oil to the threads, next gently tighten the nut (again no pun) and push the shaft all the way in, oil will leak out but that is okay, you will then tighten the nut and the shocks should be perfect.

To clarify what I do:

1) The "nut" is actually the double O-ring shock cartridge that allows the shock shaft to move without letting the fluid out.

2) Fill the shock bodies with oil (up to the internal threads) and let it sit upright for several minutes to let any air bubbles out.

3) To "gently tighten the nut" means leave the cartridge backed off about 1-2 turns to allow any air (and excess shock fluid) to escape when doing the next step.

4) To "push the shaft all the way in" should be done VERY SLOWLY and then hold it all the way in while tightening the nut.

Other things to consider:

1) What shock pistons are being used
2) What weight oil to use
3) Condition of shock shaft. Is it smooth?
4) Internal spacers for control of droop
5) External spacers as travel limiters
6) Matching overall length of shocks from side-to-side

Then, they should be perfect.

what you said is exactly what I said, and I know how to rebuild the shocks, I do them after every race, and also, you shouldn't really have to let them sit to let the air bubbles get out, the bubbles are fine as long as there aren't many of them, the shocks tend to act the same with few air bubbles as they do with none, and also, shock lenth does not matter to a certain extent, the shocks will level out as you run them, that is what Todd Hodge said in his forum a couple of months ago

I feel you should have a little bit of air in your shocks to help with the rebound. Not big bubbles but little ones are good. From my experiences the shocks dont want to rebound if there is no air in them. Rebound should be somewhat close. You should have a pair of shocks that rebound either good or crappy. You don't want one shock that is rebounding good and one that doesn't at all. Both of them should rebound little to not at all or rebound way good. Just get them to rebound so they both match from left to right. Shock length is not gonna matter if you adjust droop via shock length.

You basically take out the diff balls and replace with sandpaper pads then tighten down, I use Loctite on the diff nut to keep it from backing off.

Try Acer Bearings, they are made with quality grade 3 ceramic balls and are very inexpensive(60-100$'s) depending on which type you choose.

I gotta think that most Losi team drivers use the Trinity ceramic bearings.

I have a set of Trinity's in one car and Acers in the other. Cannot tell any difference. Think the Acers are slightly cheaper; so, I would likely go with Acer whenever I need ceramics again.

those are aluminum rings, they reduce the expansion of the diff outdrives under power, if you are running stock or 19t they are not of need, but if you run mod you will want them, the factory drivers also run bk bones, which have bearings on the pins of the cvds, they outrives that you pointed out are cutom made, you will have to make them if you want them
