Regarding the ergo shifters not shifting, I've seen that several times. There's a tiny slot behind the gears and a corresponding tab on the hood that needs to fit it into it. If it doesn't you get the frozen shifter experience. It's very easy to get bar tape in the way. I've had some success cutting away a slice of bar tape there. Usually I just avoid the area while I'm wrapping and accept the bar spot it leaves on the side of the hooks. If you see one of my bikes with a piece of electrical tape on the side, that's why.
