Removing "Posted on by WeekendPick – Leave a Reply"

Removing "Posted on by WeekendPick - Leave a Reply" Thank you so much for your help on my last question. Wondering if you can help me with three more items. These questions pertain to the site WeekendPick.com. 1) Is there a way to remove "Posted on by WeekendPick - Leave a Reply" on the Homepages and Category pages." Also once removed I have a feeling the line spacing will be off from the "Post Title" and the "Description Text." Is there a way to fix that if its a problem? 2) For the homepage slider is there a way to make it full screen to fit 100% across any screen size? Right now it cuts out at 1600px wide. 3) Is there a way to make the Category Header text larger. For example on Page (http://weekendpick.com/boston/lounges/) it would be great to make the text "WEEKENDPICK: LOUNGES" as large as the title text size.
