I would try flushing the shifters with a degreaser, rinsing with water, thoroughly dry them, them generously lube them. You might also look at the assembly of the shifter, with it removed from the bars, and look for any debris stuck in there. The shift lever not moving independent of the brake lever sounds like there might be an obstruction of some kind in the levers.
That's about what I've done, but somehow things are still gummed up, I guess. Replaced the cable housing, cleaned with solvent, cleaned with water, lubed with Triflow.

It's worse than ever now.

There's no evidence of a crack, upon close inspection. I'll try cleaning again.
