You can edit a sub-patched mesh, but if you create a five or more sided polygon while doing so the sub-patch will break. You can switch it over to Catmull Clark while modelling, that way it won't break, just remember that you are in that mode and change it back once your finished doing what you're doing, or not if you intend to keep it as a Catmull Clark sub-patch. I would recommend turning off the cage and getting used to editing directly on the mesh, it's easier that way. And I always hit TAB a lot just to see what the mesh really looks like, and correct any glaring tangles, if it looks confusing and ugly in it's raw faceted mode then it will probably not look as good as it could as a sub-patched object. It's pure chance I was here today, I haven't checked in for years.
