Removing Post Author and Date Information

Okay, been a long while since I have been around here, and that long since doing any custom work. I know I know the answer to this, couldn't find it anywhere through forum search. I do not want the author of the post, or the date information showing up, especially on the front page where the three 300x250 pictures are posted. How do I go about removing this?

And secondly, on pages that I do not want any mention of comments, how do I get rid of all mention of it for those pages?

Thanks In Advance,
Brad
