Just a bit of advise, you don't want the front and rear to activate together. When equipped with a selectable locker front and rear, 80% of the time or more you only need the rear. You only want to use the front when it's really needed, since it will effect the steering when engaged.
Some Selectable setups are wired in such a way that the front can not be activated unless the rear is.
As far as gear setup, it's well worth the money to have a good gear shop set it up. Diff failures due to poor setup can get expensive quickly. To bad your not on the west coast, we have a great guy here in Nor Cal and Crash is the man up in the Northwest.
By all means do go for getting the front setup with an Eaton or ARB, it's totally cool when you lock the front and can just ease over a tough obstacle without even spinning a tire.
