Agreed with regards to guages, but if you do end up buying higher tension strings so as to get a lower action still, this will require extra work from the neck. As a result, a setup will be neccesary, and if the neck is decent it will settle, if it's cheap crap...it won't
Also remember that a new (top-load) bridge, assumung you're retro fitting, might not line up with the existing bridge screw holes....so will need to be fitted properly
Oh and a massive +1 for Newtone, I've always found ringing them quicker. You might not get hold of them now until Monday, but they'll definitly sort you out!
