How to change iPhone Calendar settings?

I'm sick of getting notifications on my Iphone about people's birthdays (Facebook friends), i don't want to see it on my calendar, every time i click it off, and after i sync, it reloads my hotmail calendar with all that junk, how can i turn it off?

Settings>scroll to Mail, Contacts, Calendars>scroll down and turn off "Shared Calendar Alerts" & "New Invitation Alerts" and i think it would be a good idea if you just turn off your E-Mail on your iPhone.
