I recently added a Wordpress slideshow plugin that you can see in the right sidebar at my site.

As you can see, a few things wrong with that part of the screen.

Here are my questions:

1. How can I bring the right edge of the middle column over more to the right, so that it leaves a very small amount of white space between it and the beginning of the right sidebar (like it is on the left side of the middle column)?

2. What do I have to modify to make the entire left side of the right sidebar in-line? As you can see, there's a rugged edge there, and I'm having a hard time getting that left side of the right sidebar aligned properly.

Thanks in advance for your help.
