[SOLVED] how to remove post details?

I am sure it is a silly question but I can not find the answer in the forum, I am a beginner and I don't want to give up!! Please, give me a link if you know the thread

In ATO > EditPOST-PAGE INFO ITEMS I tryed different configuration (see attachment) and to me the most logic version is to have the FOOTER (Multi Post Pages and Single Post Pages) totally blank... but the info are still there (see attachment) !!

I am using Atahualpa 3.4.6 and WordPress 2.9.2.

Last question, connected to the main one.... how can I avoid the get "Comments are closed." displayed at the end of the post?

I hope someone can help me.... many thanks in advance
