3) Aerator pumps are not self-priming so you'll need to be underway to get the pumps to prime. Impeller pumps are self-priming.
I'd keep the seacocks as a safety item should you want to leave your boat in the water for an extended period (i.e. weekend). This way you can shut them and not worry about a leak developing that could sink your boat.
Seems to me if you are going to re-do your existing system, I'd go with a couple of impeller-based pumps.

1. Not true.
2. True
3. Not true.
I have one intake in the bottom of my boat that goes to a manifold with three aerator pumps on it. You just need a check valve on the fill lines to make sure they dont suck the bags dry while you are moving.
I fill all my bags at once while sittig still. 2100lbs in 5 minutes.
There are pros and cons to both.
