First off, this part of the job is the design work, once you start building the parts to be strong enough to live then you're engineering.
It would be advantageous to run a drop knuckle, but not necessary. The drop knuckle (or more drop if you already have one) will lessen the angle of the arms at ride height and raise your rollcenter, but unless you plan on really driving this thing hard, I don't think that you wold need to worry about it. You would probably feel more of a difference if you just ran high quality shocks. Calculating rollcenter is getting pretty involved on an adjustable suspension vehicle that will probably never see the track. I am however impressed that you are taking it into consideration, as it IS important that the instant center is on the opposite side of the vehicle, otherwise you will never keep camber under control.
