I want to go to
My phrase a day calendar says I want to go to is "Quiero irme a". Is "me" necessary or just for emphasis?

Just a few examples to add to what Annie has said.
"Ir" = to go
"irse = to go away, leave, depart, "split" "outta here"
Me voy = I'm leaving
Vete = Go away!
Vamos, = we're going, we go ( as a nostros command ) let's go!
Vámonos = Let's get outta here! (out of here)
Not too hard, huh?

Irse, I believe , has a stronger impact, it means you want to go away from where you are now, to wherever.. Quiero ir a pueblo. I want to go into town.
Quiero irme a Mexico ( I want to get out of here, I want to go and live in Mexico).
