So that hint got me a little further, however, I think there is still a misunderstanding on my end because I can't get all the way to where I need to be. I think the difficulty is that I would like the sidebar-a to be approximately 225px and sidebar-b to be approximately 450px and I'm not seeing how to uncouple them because it seems that any change I make to rt-grid-2 affects both. Please let me know where I'm going wrong.
I added the following to my gantry-custom.css
div.rt-grid-8 {width: 560px;}
div.rt-grid-2 {width: 225px;}
#rt-main .rt-container .rt-push-2 {left:185px}
#rt-main .rt-container .rt-pull-8 {left:-580px}
and that made the center section smaller and shifted it to the left which is great, however I cannot get the sidebar-b section to be any wider than it is now. The pictures you see there are supposed to be next to each other, rather than on top. In Firebug I can see that the "container" for the module is only as wide as the white line above the pictures.
