You'll have to remove the distributor and the clamping plate from the
block. Once you have done that you can work on the clamping plate so
that it allows the distributor to turn.

Common. I don't think there is an MGB on this planet that idles at 600
rpm. Don't forget to disconnect and plug the vacuum line to the
distributor.

Better performance, but don't advance it too much or your engine will
ping.

Checking and changing the timing is part of a package. Just doing the
timing is not going to work unless everything else is perfect and the
timing has gone off because of a loose distributor. I would give the
car a full tune-up (adjust valves, bring the ignition system up to speed,
check and adjust the carbs).
