Check also for leaks around windshield and other windows. My car looks nice from the outside but it leaks a bit behind the chrome trim. That could affect the floors also. Once you start her, check for other leaks (oil, transmission fluid, etc). Sentimental value is one thing but you do not want to end up with the car that needs body work plus other things like engine or transmission rebuild.
We do not want to discourage you but you need to be realistic and compare the work required with the money you have and/or willing to spend on the car. Like David said, body work is usually the most expensive part of the restoration.
