Import contacts from gmail, yahoo, hotmail facebook and twitter

Question

I need to import contacts from gmail, yahoo hotmail and facebook and much more, I know about google api. Are there any libraries that allow me to import all contacts or should dirty my hands by writing codes using all api's.

And also I need to insert the html code into the email, and I have to send it through my friends.

I use javascript on the front end and servlets on the back end
