Movable Type 4, CSS, and A Deficit In My Knowledge

Does anyone out there know CSS?

I've been doing video editing for so long that my technical skills are really sub-par at this point. It has taken me all day to get the site up and stable. Right now what we have for the site is a built-in template called "New York" or something like that. Of course, I want to get our pictures up at the header, and it'd be nice if it could be an image map so that you would go to an author archive when you click on a picture.

But I have no idea how to do that, and I've spent the last hour banging my head against a wall of CSS. I managed to get a white background in front of the old That's Plenty banner, but it looked so bad and didn't offer any clickability (like to get back to the main page) that I've just gone back to the default css.

Now I know why people hire people like me to do their computer work. I know if I bought a CSS book I could figure it all out and get it looking exactly how I want it, but my time is limited and there are about 500 things I'd rather do than learn CSS.

*sigh*

Anyway. Come! Celebrate! The grand re-opening of That's Plenty! Watch your step, I haven't covered up the manholes yet...
