Layout mod, Slider rollover/click, embed vimeo layout

Great template.  Can't wait to see the pro version. 1.  I'd like to modify the layout defaults.  Appearance>Layout Options> Right/Left/No Sidebar dimensions.  They work for most of my pages on the site, but on this page,  http://www.nakadavfx.com/?page_id=51 , I'd like to widen the No Sidebar to utilize the full width so there are less carriage returns (currently I'm abbreviating but I don't want to). And on this page,  http://www.nakadavfx.com/?page_id=31 , I want to decrease the Right Sidebar width for the same reasons. Since the 3 defaults work for most of the site, I'd like to modify only these particular pages. 2.  Also, in the Featured Slider Post, is there a way for the title and sub-text to disappear upon a mouse-rollover.  http://www.nakadavfx.com/.  And on mouse-click, open in a gallery (I like the gallery overtaking the screen with the option of the full rez button) 3.  http://www.nakadavfx.com/?page_id=8 , here I have embedded vimeo clips.  I'd like to have 2 columns of videos.  I can shrink them down but can't figure out how to make them be side-by-side. I have gone through the entire support forum before posting, sorry if I missed these somewhere. thanks, ken
