Trying to list more than 3 columns per row...

I've done due diligence researching this topic before joining the forums to post this. Regardless, I'm sure someone will know the answer and prove my stupidity :)

Here is my site:

I have installed the Emeralda theme and removed the columnone and columntwo (left and right columns) trying to make space for additional columns, but it seems no matter what I try I can solve it. I've tried reducing margins, padding, adjusting values in the maximum values (I've tried 4, 5, 6, 10 -- any value to force it, as some people have said it worked for them). Nothing changes it. Stays divided into 3. I've managed to reduce the width of the rows, and have them shift over to the left, but it remains only 3 rows. I've tried to force using some css I've ready amongst several different threads. No luck.

I have now installed the column layout grid add-on for zencart and messed with those values. I keep getting the center grid displaying 3 products wide only (dividing dynamically by space available and 33%). I've adjusted my full page to 1024 pixels because a) I want the space and b) I thought it would help the center column dynamically divide into 4.

Any help much appreciated. I'm a newbie to CSS, but I'll figure it out with some help :)

ALSO -- the background for the headings (example: "New Products For March") is only displaying the same as original length, so I'm just getting a white background behind the header text. Let me know if you know the solution for that, too. Thanks!
