Graham,
There's no easy answer. It all depends what you intend to run on it and how you intend to use it. For example, standard gauge stock has a relatively narrow profile, so will not stand as much gauge widening as narrow gauge stock. On a siding, superelevation doesn't matter but on a running line it does. If you check the society's standards, you'll see that 1/8" is the maximum (according to that standard) for gauge widening. And if you have vehicles with a wheelbase much over 18", you're going to need that with a curve as tight as 30' radius.
Superelevation - the issue I've always had with this is that it encourages a certain kind of person to drive far too fast round the curve, so my personal opinion is to keep it light, if only to deter the ignorant.
Regards
Peter
