Some free movement at the top of the pedal action is normal and necessary, to ensure the master cylinder is not exerting any hydraulic pressure and the clutch is fully engaged. I think from my gropings under the dash that the pushrod to the master cylinder is adjustable length, but half an inch sounds about right to me.
[edit: the noises are annoyingly normal. Pedal creaks and clicks are usually the return spring and/or the pushrod. Aside from endless lubrication some have reported improvement by adding a flat washer or two to the end of the pedal pin that the pushrod mounts on, then replacing the weird Alfa clip. Doing this supposedly keeps the pushrod from twisting and misaligning with the master cylinder. It's also worth squirting silicone grease at the point where the pushrod enters the master cylinder boot. I've done all this aside from adding a flat washer, and currently have just a trace of creak that can wait til warmer weather.
It doesn't sound like your master cylinder needs replacing at present, though if you do, some silicone or rubber grease on the pushrod end may help shut it up.
