is there a way to figure out how many contacts i have in my phonebook without having to sync n looking in outlook?

At times when I have to block my number, instead of memorizing the persons number to put *67 in front, is there a quicker way to do it or if i store it saved with *67 and other times i dont want to block is there a feature of that sort?

Also for some reason some of my contacts have all the numbers with area code bunched together where as others have them with dashes (ex: xxxxxxxxxx vs. (xxx) xxx-xxxx
I have tons of contacts is there an easy way I can get all of them to have the proper format versus doing it one by one? thanks
