Learning about Keys and Locks, Wafer Source and Questions Options

[Highland]

With the exception of the front trunk lock I've had to reconfigure the wafers in all my locks to get the key to turn smoothly. Everything has been keyed with the black key, the red key seems to not be for this car.

I'm working on the ignition key now and the key turned enough to start the car, but sometimes would catch and require a little wiggling. After opening the assembly, I notice some of the wafers stand slightly proud above the cylinder.

Does anybody know:

1) Do the wafers wear over time and I actually have the right wafers?

2) How many wafer types are there?

3) These wafers on ebay match dimensions. Any opinion if these will work on our cars?

Prior to rebuilding the locks, I placed each set of parts into a Tupperware, sprayed in some brake clean, agitated and then lubed with a Teflon dry lube. You need to remove the old gummed up grease from all the parts. The shiny wafers were black before cleaning.
