You could replace the Zener with a large
capacitor. Leaving Rs at 200 ohms, and simulating for 1 second
(remove the Ncycles = 5), 2200 ?F gives about 16 mV
peak-to-peak. Capacitor current is only about 10mA peak-to-peak.

There is no practical answer to that
question. The lower you make R2, the lower the ripple on V(2),
but the Zener current goes up without limit. See if 100 ohms
reduces the ripple enough for your application. If you change
the Zener to one that will carry enough current without
burning out, you might be able to use 50 ohms.

I am basically looking for how to optimize
(calculate) the value of RS to obtain a minimum output
ripple r2.
