As a start.
I would suggest some form of toob protection like a sheet of ply to dangle over the side for the locks, as they are mostly original stone built, or a good replica of same for those they had to move out the way of a road.
have a fair few photos to give you an idea of whats out there. Probably be able to give you some advivce as well.
Food wise, There's an Italian by a saith in Falkirk (Forth side of the wheel), and a reportedly good Restaurant at Auchinstarry Marina. There's a Weatherspoons (along with lots of other stuff) in Kirkintilloch & about 20 mins of motoring later the Stables Pub by the A803 bridge. Not so sure about facilities further into Glasgow, but the F&C bods should be able to help.
