Moving Sidebar and limiting Width without messing behavior of other pages?

I’ve been making progress working on my site; however, I’ve hit a nasty obstacle and had to delete 6 child themes (>_<) I had to change the parameters on my “Coaching Services” page to fit the entire content. In essence, I made visible the overflow and increased the width.

That change also changed the parameters for my the other pages. I’m fine with that. I’d rather not set it back; however, my “Blog” page is funky. First, when I make visible the overflow the content runs over the sidebar. How can I decrease the width and move the sidebar without messing with the behavior of the other pages? A template?

Second, I’ve made changes to this and floating it right changes the behavior of my content on other pages, such as “Coaching Services”. How can I move the sidebar and blog posts and make it so that the entire snip-it is not being cut off?

#content #left-col {
float: left;
padding: 20px 16px 20px 10px;
width: 620px;
z-index: 1;
}

Third, the individual blog post page is a default page with the side bar. How do I move this sidebar and decrease the width of the post without messing the behavior of the other pages?
