Italian mother in law? HELP!

Long story short, my fiance is saying that he is ready for me to meet his HUGE Italian family (as in EVERYBODY) & well I'm NOT Italian so I don't know the "Italian ways". I'm mixed, mainly Hispanic...& I've heard that Italian moms are NO joke...so any pointers to fit IN? I've also heard that many Italian guys are "mommas boys"? please help me out, I'm just a girl trying to make my life filled with as much love, harmony and happiness as I can. I LOVE my husband to be & I want his family to be my family. :0) ...well their about to be MY family too lol...soon.
