Heatmap theme help - author/date etc

I'm in the middle of making a new MNS and I'm using the free version of Heatmap.

I've some questions though, how can I :

Remove date from posts/pages

Remove author from posts/pages

Remove "comments is closed" message (I've got rid of the comment box)

Once I have all of this done I can start writing content!

Surely someone here has this theme and can help me out ?

Thanks

Got it sorted.

Had to edit some of the .php files
