Twitter issues; hashtags, at-tag. &Socializer global disable

Hi

I would like to remove the @sharethis tag coming up when someone clicks on twitter share.

I would like to put a hash-tag.

I would like to change the shortlinker to bit.ly. I’ve already setup the bit.ly API but it doesnt seem to work.

I’m using only shortcodes because there is no feature making the “global buttons disabled, unless I make it show on individual pages/posts/galleries”.

The shortcode I’m using is the following:

Also, I fear the twitter counter is counting wrongly. There is no way to put a hashtag, therefore I can’t just search twitter to verify.
