G Limits in aerobatic aircraft

Ok am probably going to show up my woeful knowledge of physics and aerodynamics, but here goes.

If an aircraft is certified for a max +/- G loading then presumably;

1. This G load is permissable up to the VNE. Put another way does the stress on the airframe increase with speed or does the total G load "capture all", as it were.

2. Even I know that "compound" manouvers put additional strain on the airframe (I suppose a lomke..whatsit being the most extreme example i can think of) and back when i flew only spamcans one was always warned to be very careful of multiple inputs (like ailerons and elevator in concert when recovering from a spiral dive). So is it the case that again the G meter catches all and the spamcan warning only applies because it doesn't have one.

Have a feeling I am about to get a 101 on aerodynamics and loading but the hard hat is on and I welcome all thoughts!
