Request For Shot Code

Hi, I just applied the CatchBox pro theme to my website: www.wmlcloud.com. I wanted some minor changes to the theme which I hope can be made with a custom CSS code that you guys can provide. 1.    I would like to increase the width of the desktop version of the theme to 660, without affecting Mobile UI (not the sidebar but just the main area). 2.    The “About Author Name” section below posts is in H2. I would like to use just a Bold font for it instead of an H heading (for SEO reasons). 3.    I would like to hide Tags and category name (below excerpts) from Home Page and Archives. I want them to show on pages and posts but not the Home Page or archive pages. 4.    The ad units are overlapping the Mobile UI. I’m using the Quick AdSense plugin for showing ads, since it allows me to show ads just after the title and at the end of the post which is recommended by Google.  Is there a way to fix this e.g. by slightly increasing the Mobile UI Width?
