any combination of transfer case shifting is acceptable. low with the front case and high in the rear case in just fine. But be warned. If you use low in the front case, and High in the rear, the amount of torque put on the input shaft of the second case is multiplied by 2.28 (assuming you have 2.28 gears in the front case) This extra torque may cause your input to break. Generally speaking there shouldn't be a problem, but if you find yourself bouncing with your foot to the floor and the front case in low you should probally stop and re-evaluate your line choice.
I hope that made sense.

Yep, you now have a real 2WD-low range with the front stick. I use mine all the time, great for backing out of tight parking spots or on really steep hills, and it is perfect when you get stuck in extended stop-n-go traffic.
That said, for off-road use, you generally want to use the rear case in low range first before you put the front case in low range. Reason being that the t-case input was really only designed for the 1:1 output of the transmission, not the extra 2.28:1 or whatever you front case it. Some of the earlier dual t-cases (mine included) had the weaker OEM input shafts and bearings and wore out over time. I used to always use the front (2.28:1) low range and then the rear (4.7:1) low range only when terrain got difficult. Eventually I stripped all the splines off the input shaft.
Now I put the rear case into 4L for 90% of the time off-road then only use the front L when needed. I do end up using 3rd and 4th gear in 4L if the trail eases off.
For for on-road, front L - rear 2H is fine. For off-road, you would use (front-rear) H-4H, then H-4L and finally L-4L.
