1) As alliance, is it faster to fly between the two ports in kalimdor or to take a ship to eastern cont and back to kalimdor?

Take the boat twice. The flight is ten or more minutes long, and only the worst boat luck will approach that.

2) Are there any quest items in particular I should hang onto after quest chains? Most of them seem pretty disposable.

Most of them are. Off the top of my head, only the Chained Essence of Eranikus (which keeps pointing you to a further step anyway) and the Black Dragonflight Molt (which Kalaran specifically tells you to keep) are important.
