Lots of folks here use Bilstein shocks, so you may want to check them out.
For the rear, you will need to buy two 3-5 Ohm 50 watt resistors, one for each shock, and solder them across the 2 Wires that connect to the shocks. I suggest doing this in a way that you don't have to cut off the connectors, or at least don't throw them away, just in case that you want to convert back to OEM in the future. This will eliminate the dash warning for the air ride suspension error. These resistors can be purchased on Amazon, by searching for air ride delete resistors. If you want to spend the money, they have kits available which simply plug into your existing electrical connectors, thus eliminating the need for cutting and soldering.
I will also say that I don't know what impact or drivability issues you will have, if any, with having the front shocks electrically changing the stiffness of the shocks, and no corresponding changes in the rear shocks.
