Website help CSS and PHP - basically Blog editing

Hi guys.

Its time for me to ask for help again.

I'm making a new website for myself and I'm stuck. My needs exceed my capabilities, but this is where you come in.

On my website i have a "What's New" section. This will be a blog page and im planning on using PivotLog as the blogger software. Now, the defaults all but fit into my layout and colorscheme. Can someone please help me edit the CSS and what else is needed. I am very new to this but would like to have a cool website and you can be sure you will receive props for your help. If you need additional info please let me know.

Here is the page where i want the blog inserted into the middle section.
