Number of seasons is irrelevant. How many days a season do you ride? If it's one, you can probably get away with the same equipment for the rest of this century.
What you describe for the board is normal wear and tear. This is like measuring a car's quality by how often you have to change the oil... It is by no means a yardstick for durability.
The binding cable fraying and the back of your boot splitting may be linked. Try re-aligning and re-adjusting the setup on that foot from the ground up. You might be pushing the high-back into the back of the boot way too hard or something.
It's too late to salvage to boot with anything short of marine grade epoxy, and even that might not work.
EDIT: I tried keeping the first new board I ever bought scratch free.... that lasted about five minutes into the first run before I gave up. You get a board to beat it like a rented mule, not rub it with a silk tampon.
