Kind of starting over, then, with my questions. Anything else need replacement to change just the smallest chain ring?
If this is what you have, looks to be of decent quality. (I'm not familiar with it.)

You would have to remove the drive side crank structure to get to the inner ring. You would have to first locate an appropriate smaller inner ring. FD would likely need fine tuning with smaller ring.
