(1) Is the rubber seal at the end of the hose supposed to be
sufficient to keep the joint water tight?

It is sufficient.

I do not think I am over-tightening the joint. If anything I may be
under-tightening it as I'm tightening by hand and, at my maximum,
probably could give it another 1/4 or 1/2 a turn.

Hand tightening should be enough. If not look at the sealing faces.

(2) Is it good practise to use PTFE sealing tape on these screw
joints?

No.

Take a look at the fitting and think how it prevents the water
coming out. The washer is sandwiched between two faces (one on the
hose and one on the pipework fitting). Putting something on the
thread is not going to do anything useful, as the assembly does not
seal on the thread. If water is coming out then there is a problem
with the washer or one/both of the sealing faces.
