Google says that's a non interference engine, so you shouldn't have any engine damage.
I also have a 94 Escort 1.9L wagon. The timing belt isn't too bad. The water pump is more difficult, because the working space on the passenger side of the engine bay is extremely limited!
It's not rocket science, so don't worry about it too much. Just bring a lot of tools and be ready for a serious pain!
Also pull and check all of your hydraulic lifters! The wrist pins like to wear and drift sideways out of their bore, which starts carving aluminum out of the head.
