"without further ado" = "without any more delay or distractions" or "Let's get on with something more important" ado means time-wasting over trivial details. Usually it is said when a speaker is introducing another speaker and the 1st one has said all the details about the 2nd and has complemented him/her enough.

It just means "without further delay."

This phrase is used at weddings, conferences etc whenever a new speaker is to be introduced, it means without any more delay.

It really just means: "Without further delay or distractions." It can certainly be used to introduce someone: "Yada, yada, yada... And, without further ado, I give you Mr. X, the famous illusionist." It's certainly not used in that context exclusively, though. Like: "Without further ado, the couple went to the next inn." Etymology: Middle English, from 'at do,' from at + don, do; to do.

fdmaxey is correct, but it is not just limmited to introducing a peron(s), it is used when introducing a new subject or idea aswell. it is sometimes said after an explanaition.
