Wordpress Expert Needed

I use Wordpress and I need some customization so that my blog will behave and look like [login to view URL] I have already created the horizontal scroll bar so that does not have to be made. I will give you the code for that so you can implement it into the blog, but I need for the pieces of my blog to fit in my Wordpress site horizontally (not vertically - default). I use the following plugins: Dynamic Content Gallery [login to view URL] YAPB [login to view URL] and these need to fit side by side next to the newest article that is created. So I need to artcles that I write to either have a scroll bar or flow into multiple columns so that they stay within the confines of the scrollable wall. I need this to be created so that I can easily upgrade to a newer version of Wordpress when it is released. So a plugin would be great or working in just a few files (to minimize effort) would be nice. This seems to be a simple customization of the [login to view URL] file so that the layout is horizontal and not vertical so this shouldn't take too long to modify.
