I can't claim to be a constitutional expert on the 2A - but it seems to be alot of balancing going on there. "well regulated", what does that mean? OK, to keep arms is clear - but where can I "bear" them? anywhere I want, without restriction, including concealed carry? I don't know.
I'm not in favor of federal gun laws, I think a state based system works best.
Not at all - the passage is explicitly clear.

It means well trained. Nothing more than that. That can be determined by reading the Federalist Papers, although I can't recall the exact cite off the top of my head.

The Founders knew - "shall not be infringed". That means anywhere, without restriction.

Unfortunately for you, the 2nd Amendment preempts a state-based system of gun control. Advocating one is by definition unconstitutional.
