If you do a search, you will find all kinds of posts on trips to Italy.
I would completely agree with the suggestion to stay at Fonte de Medici if you are going to Tuscany but I can't say the same about going to the Osteria do Passignano. Too expensive, stuffy and you don 't want to be limited to their in-house wine list. Try Scuderia across the road from the Osteria in Passignano - or better yet, go to Enoteca Fuoripiazza in Greve. You will have a much better experience.
