[Plugin: Twitter Tools] How to change display

I would like to add post title to the tweet as well as the URL.

Currently in the Twitter Tools options,

I can only add tweet prefix (which is defaulted to ‘Website:’)

How can I
a) get the post title as text in the tweet
b) ensure my bit.ly shortens the post url.

Many thanks

Mark
