Always in gear, always handbrake on.
I always depress the clutch to start the car. This is primarily because I've owned cars where there's a clutch switch, so you have to depress the clutch. Quite frankly not bad practice in a manual transmission vehicle. There is actually no reason for the starter to be turning over anything other than the flywheel. I know there's probably no issues in practice, but it isn't a bad habit.
