All depends what you want personally, and how much you're willing to spend. The guys who already replied pretty much summed it up..
I have a front to back setup on mine, with 1/2" Fills and 3/8" Dumps.. I adjust my lift speed with one of these right before each fill:
Theyre pretty small, and if you ever find a small leak somewhere, you can shut these while youre parked for a while so you dont lose all your tanks air.
Remember 1 450-460 per 5-6 Gallon tank.. and if you want gauges, you have a few choices.. but like my setup, I have one single needle for the tank, and one dual needle that reads the front pressure and the rear pressure.
Bags are kind of a personal preference too, but you said you dont wanna hop and run high PSI.. so Id recommend Contitech 2 Ply Single 1/2" Port. They are good quality bags.
As for the valves, if you have to spend a little more to get a good brand its definitely worth it IMO, because you for sure dont want them ever to stick.. due to moisture and being cold, or rust.. that could be dangerous.
For your front brackets, a regular set of minitruck torsion brackets is what youd need.
The rear is always the hardest part since there is so many possibilities, you have to decide which type of notch you want, then install it accordingly for what wheels you plan on laying on. You then gotta figure out what brackets you want, you can do on the link bars, over the axle, behind the axle, or probably the cleanest.. behind & under the axle. Then comes the link setup.. of course a 4link is the best overall if installed right, a 3link is also really great though.. you could maybe do a 3link, to save a little.. since you dont want side to side anyway. 3 or 4link wont give you pinion change, wheel offset in the fenderwell, or anything like that..
other than that, theres small choices like switchbox, the way you want to plumb your system determines what fittings you need..
Sorry if the whole thing I just typed is unorganized, I just typed all I could think of.. maybe some of it can help you LOL but hit me up on aim or email me if you have any more specific questions, I'll do my best to help.. I always have time. Good luck man!
