De más está decir que

Question

I hope this says "Needless to say".

Gracias.

Answer 1

You are correct: "Demás está decir" = "needless to say". Perfect.

Answer 2

Yes! Good equivalent! (Also equivalent to "It goes without saying.")

Answer 3

I've never heard this. I have heard ademas which means more like besides.

ex.: Además, él ya sabía.--Besides, he already knew.

you could say: No hace falta decir, él siempre gana.--Needless to say, he always wins.
