i want to get my ReTweets too. what i should use for that?? do i need be authenticated for that?

Newtwitter has an API method to get retweets by a user. You would perform a GET request to https://api.twitter.com/1/statuses/retweeted_by_user.xml?screen_name=xyz

You should also update your existing request to use the correct URL and API version as specified in the documentation.
