Couple of minor issues on a wordpress site

First, as you can see there is an error on the site ([login to view URL]) and it will not properly show the Jtabber plugin on the front that normally works perfectly. As a consequence of that, it is preventing the "featured content plugin" from displaying and you can see the large blank white spot. The second part of the project is just basic cosmetic css stuff. I want to add a bit more spacing between the different little widgets in the left sidebar, as well as on the right sidebar. I also want to make the main page article box (dark grey) a bit less wide so that it is equally as wide as the jtabber plugin above it. I need someone who can start and finish this project right now!
