How do you do? Is rarely used...save it for when you're introduced to the king. It doesn't mean 'hello, how are you?'. I think your list of alternatives is MUCH too long. Who uses 'howdy'? Maybe cowboys, every now and then. Stick with the useful phrases and focus more on pronunciation and intonation!
Salve molto brava fai corso di iglese dove?
Sei meravigliosa...
Sei troppo gentile!
