adopting a 2 year old

My husband and I have never adopted before we were just chosen for a 2 year old and since we have never adopted or had any children... We don't know exactly what we need for a 2 year old, we are going to change the crib to a toddler bed but other than that we don't really know we had all the stuff for an infant but when they asked us about this child we just couldn't say no... so if everything works out what is it we absolutely need. also does any one know of good ways to break the ice when meeting the child, I know she had a stuffed animal in the picture we saw of her so We bought an outfit with it on the shirt, and then plan on buying another little item for her maybe a little purse or something... I just feel bad in a way because i know its going to be hard for her so if there is anything i can do that any of you know of it would be very helpful. Thank you
