What is a good age to stop the pacifier and start using a big boy bed?

OUR SON WILL BE 2 YRS OLD IN JUST A COUPLE OF WEEKS AND WE ARE LOOKING TO CUT OUT HIS PACIFIERS AND START USING HIS TODDLER BED INSTEAD OF HIS CRIB. I AM NEEDING SOME GOOD IDEAS ABOUT ELIMINATING THE PY AND A GOOD WAY TO GET HIM ADJUSTED TO A BIG BOY BED, AND IF WE ARE STARTING ALL THIS TO EARLY I'D LIKE TO KNOW.
