Wordpress Theme Modification

Hi Freelancers, I'm wrapping up a WP site and have a few theme modifications that are a bit beyond my depth. The dev site is located at: [login to view URL] 1. As you can see in the attached screenshot, the media player breaks to a second line (by what is probably just a few pixels). I think this could be pretty easily fixed by simply adjusting the padding in the Overview section's css, but couldn't quite find the correct line and didn't want to mess it up. 2. Is it possible to modify a page template to remove the sidebar from post pages in only a specified post category? I'd like to remove the sidebar from the post pages of posts in the 'Featured' category (created via 'Featured Posts' in WP menu), but I'd like all other posts (news/blog) to retain the sidebar. 3. Featured Posts are pulled into the Slider section on the homepage, and I'd like to modify the slides in two ways: a. Allow a larger image to be displayed (added via 'Icon' meta box and currently limited to about 80x80px). I'd like to remove the size constraint completely if possible. b. Allow a media player to be displayed on each slide. When I add a media player to the post, along the the text content, the theme strips out the media player, only displaying the text. 4. Center video thumbnails in Video section on homepage. Alignment is currently set to left, so unless I use exactly 4 videos, they are not centered. 5. The video light box has too much padding (horizontally as well as vertically). I'd like to remove all padding if possible, for a cleaner look Please let me know what questions you may have, and I can give wp-admin creds as well as FTP etc... Thanks!
