Actually, it's helpful to tell EWR ramp your departure fix. They (sometimes) are aware of stopped fixes or fixes eligible for runway 11/29. Or don't tell 'em, you'll find out when you call ground or flow.
The "b" at the end of the gate number (B61b) is from the good ol' days when there were a lot of widebodies flying around. First class would have their own jetway and coach their's. The two jetways would Y into one. The 747's in terminal D still use that setup sometimes.
And when will guys in IAH learn that the ramp controllers in CLE and EWR could care less which fix you are flying over? At both airports you taxi out towards the runways in the same direction as other traffic.
EWR ramp controllers do care what fix you are using. They have sequencing duties. Meaning, they will not give ground two COATE departures one right after the other.
