Ok, the whole purge valve, canister, canister valve thing is all BS. You caused it by overfilling the tank. What happens is you put too much gas in it, it floods the canister, the little bits of charcoal float up and clog the evap system, the purge valve, the canister valve, etc. Yes, they can fix it by replacing all that junk, but it will cost a fortune. You didn't say they would replace your canister, only the valve. That's no good because the canister is the part that has failed.
Just remember that your evap system being FUBAR like that has no effect whatsoever on your fuel economy or performance. .The problem it makes it hard to pass emissions, which you apparently have overcome.
You didn't say what codes you got at AutoZone. It's important to know that, so you can do the cheap fix. Sounds like they take you for a "mark".
I wouldn't bother with the "intake clean" or the "fuel injection clean" unless your getting codes for fuel injection problems, or you're getting bad fuel economy. Your dealer sounds like they want to make some quick bucks.
You got 68K miles. Did you change the timing belt?
