Height measurements are very subjective, since it depends so much on how much weight you have on board.
I meant stock height for stock vehicle weight....
I'd like to know how far off I am with my current setup

How long is a piece of string? The ones that I have measured were ~20", +or- 3/4". It depends on spring and load, a few different springs were used and stock rigs were configured differently (weight).
Spring design/selection is pretty complicated, but OME gives enough info to make a good guess. The way I understand it is; they are rated to lift height at load. In other words; if a spring pair is rated 2.5" lift, 220lb per inch and 440 lb constant load and is installed on a rig with 440lb of extra constant load, centered over that axle, it will net about 2.5" of lift. If installed on a stock weight rig will net about 3.5" of lift. Here again "stock weight" is the key, in my experience, the early rigs were the lightest and the LX450 the heaviest, so it is about.
As long as the springs are not abused (coil bound, etc) it is acceptable to use them with more or less weight. The resulting lift and handling will differ, but if within a reasonable range the spring will be fine.
Another question....
Do the OME rears differ left to right or are they both the same?
I recently upgraded from worn out stock springs and spacers to the OME 850/860 setup. That is heavy in front and medium in the rear. The amount of lift was just about spot on at the 2.5" as advertised based on running them without any spacers. I have what sounds like a similar amount of weight (my rig is 6,000lb daily driving) and its pretty balanced front to rear. That would probably give you maybe 1" of lift beyond the setup you're running now. The ride is better than the worn out (cushy ride?) stock springs in that it feels more controlled, with less sway. Based on what I've read I'm thinking this would be a good setup for your usage. Having the air bags will do a good job of compensating when you're loaded up too, so you probably wouldn't need heavies in the rear. If its important to you, there is no loss of articulation, if anything it is better than a setup with spacers due to not having a worn out spring, and the OME shocks are longer.
I believe OME changed their part numbering recently to add the '2' in front, to designate that there are 2 springs in a box. The 440lbs would still refer to the pair, not each.
850/860 gets my vote.
