<font color="blue">the output pipe on disposal goes STRAIGHT sideways until it meets other drain at other sink bowl. It does NOT exit disposal and do "immediate" 90 degree turn as I expected. Could THAT be part of the issue?

I guess I misread or didn't read it good enough. You need the 90 to keep the water from the sink from backing up into the disposal. Especially if the main sink drain past the disposal is a little clogged.
As far as the coffee grounds getting into the dishwasher, not an uncommon problem. The dishwasher drain should have some sort of check valve. This keeps anything from the sink/disposal drain backing up to the dishwasher.
