comment Connection and reduction of the structure group
To show that there are $H$-compatible connections on $E$, it seems to be a bit easier to take an arbitrary connection on the reduced bundle and then extend it to the original bundle.

comment Curvature of a principal bundle and the exterior covariant derivative
You can try Kobayashi, Nomizu "Foundations of Differential Geometry". Their approach is essentially the same through their notation is different.

comment Yang-Mills Functional and Energy
Yes of course you are right, my answer applies only in the Riemannian case. But as you noted, for Minkowski spacetime the norm of the curvature is not the Hamiltonian but the Lagrangian. Thus in this case the question does not make much sense.
