If they are comfortable and pretty much brand new, you could have them taken in and use them as your show boots... if the foot being too big doesn't bother you. If it does, I would strongly consider selling them.
If you are getting new boots for schooling, I would strongly consider a nice set of leather half chaps for at home... check out the Ariat lines as well as Pro Chaps and Tredsteps (they are a little more $$ then most of the Ariat half chaps, but I have Pro Chaps and love them - will be buying a new pair of them when I end up having to replace them and recommend them to everyone!).
As far as buying field boots versus dress boots for showing dressage, I think if dressage is something you intend on pursuing in the long run past the lower levels it would be cheaper and just all around easier to purchase dress boots versus field boots. Field boots and dress boots of similar quality are around the same price and if dressage is something you intend on pursuing, why not just start with dress boots and not have to go out and buy some in a few years? If you take care of them they should last...
