It does help, thanks. There's a plan of the seating on the site, and I've just noticed some of the sections have a feature where you can see a view of the stage from a particular in a little box. If that makes any sense. Sadly, the only section that doesn't seem to have that feature is the one I was looking at for the decently-priced seats. Oh well. Happily, the front row seats of the Upper Circle have already been taken, so I don't have to worry about that :)
