Are there any no-no's with regard to interpretation? I've noticed on Youtube that performers have hugely differing ideas about tempo; is this usually just a matter of personal taste? Also, in the way that a light touch is necessary for Mozart, is there a particular approach to adopt here? When I'm trying to bring out a melody myself I tend to use my ears, and my fingers will remember what to do the next time when I get it right for the first time, but I find this difficult to pass on to pupils.
Tempo is a matter of taste and technique. Played quickly by a real virtuoso, R's music is often scintillatingly brilliant to listen to, but details get lost. Played more slowly and with attention to inner detail, a listener gets a sense of the scale and power of R's music.

Is 'firm but not harsh' a fair starting point?
For sure, it is. Approaching R's piano music, it is well worth while remembering why he composed it. He fled Russia to escape the Revolution and forged a brilliant performing career in the US. He composed his piano music for his own use. His techniques was unbelievable, his hands collossal; he wrote for performance on a full-sized concert grand piano.
The secret is to think 'big' sound - as big as the piano you are playing is capable of making. Imagine projecting the melodies all around the Albert Hall. Imagine the power of a top-class soprano with a professional orchestra in a performance of Wagner's Ring cycle; R's music is the piano equivalent to this in terms of scale and power.
I am with you in the matter of
how to produce the sound. Once you get into the realms of do-this, do-that, all you tend to get is a confused pupil. By the time a player gets to the stage that she can attempt R, she should be able to respond to the, "This is the sound we want. Now you produce it as well." approach.
The only no-no I can think of is this: don't thrash the instrument to within an inch of its life in the search for volume. Just because R wrote ffff on a score, doesn't mean we can produce it. Thinking 'big' rather than 'loud' usually leads to the right approach.
I hope all this helps and that I am not coming across as being dogmatic - just offering my 2 pennies worth.
