it will be fine to ground the valves all to one spot. depending on what the valves are mounted, if its mounted to metal. you can actually ground the valve to istself. and the tank does not count as mounting the valve to metal
this is not for bags question, had it, dont like it, but you seem to know about cup kits too, so how much higher would a cup kit set you at when it is at lowest slam, cause it wouldn't make sense to get cups if you'll end up higher at full slam if your coils can't even go that low to compensate for the height of the cup kits
Bags are never going to be the same as coilovers because air constantly fluctuates. Take a turn hard and it will be easier for PSI to change than it is for a spring to compress, especially if the spring has a stiff rate.
Here's a great post on the PVIP cup kit:

About 3.5 - 5.5". It does make sense to get it because it allows you raise the vehicle. If you're not raising it, you're riding on coilovers 100% and for those that want to retain the suspension in the same way constantly, will stick to coilovers.

no they will be fine
i disagree. the reason that the psi in the bags fluctuate when you take a turn is because mose people take the easy way out and put all the valves in the trunk. which is kinda silly if you ask me. if you do it that way and lets say your gauge reads 50psi in each bag. well realistically its 50psi in each bag AND that same 50 psi is also whats in the airline thats running from the valve thats way back in the trunk all the way to the front of the car where the bag is. if you put the valve as close as possible to the bag. you will have VERY VERY minimal psi fluctuation.

8 valve setup will give you control of individual corners. not really necessary but it is kinda nice to have. but i know tons of people that only run 4 valve setups and are just fine with it.
4 valve setup will only give you control of both fronts at same time and rear fronts at same time. or whole car at same time. wont be able to do individual coners. absolutely nothing wrong with only running 4 valves. and if you do run only 4 valves not only do you save money on valves (not having to buy another 4) but also save money on fittings (dont have to buy as many) and at any point you can upgrade to a 8 valve setup pretty easily if you want to

I wouldn't do a 4 valve setup. While I was a deal for UAS a while back, Zack went into quite a bit of detail as to why it's best to spend the extra on the extra 4 valves. You'll have way too much sway from suspension travel basically because of what Kenny mentioned, each corner not being managed individually.

this is true. and the only way that you are going to really be able to eliminate ALMOST but NOT all of that sway is by running some adjustable sway bars at full stiff
