Certain parts creak, certain parts knock, some creak and knock if both the joint and bush is gone. ARB and it's links definitely knock, you'll feel it under your feet when driving. Lower woshbones appears like a constant creaking, they last longer than upper wishbones. Upper wishbones can go wrong with the joint (knocking over (speed) bumps), or the bushes can wear out. These last only around 30k miles in my experience.
You learn enough when you do the work yourself or assist the work bieng carried out.
As for airbags, connections I know of are... under drivers, under passengers, two in boot (curtain airbag connections) and supposedly the one going to steering wheel is also dodgy.
Some electrical spray works well, the ones under the seats need to be stripped and reterminated using standard terminal block.
