Image Placement

Hello, I'm new to drupal and trying to create a front page. I'm using the FCKEditor. My page is http://financialcoachtoolkit.org/

I am trying to place those four boxes in a 2x2 formation. So, I want Creating Stability and Providing Expertise on line 1, and Leading the Field and Changing Policy on line 2. I tried using <p> </p> tags to move the third box to the second line, but it didn't work. Here's what the page source code looks like:

<p class="rteleft"><img hspace="0" height="48" width="650" vspace="0" align="top" alt="" src="/sites/default/files/Welcome-to-TFC.gif" /></p>
<p class="rteleft rteindent1">The Financial Clinic is a pioneer in financial development, defining the field itself, setting the tone of the conversation, and guiding the thinking and policy behind solutions. We provide innovative financial counseling and legal support for families caught in the wage gap&mdash;where they earn too much money for public assistance and too little to be self sufficient.</p>
<p><img hspace="5" height="160" width="200" vspace="5" align="left" src="/sites/default/files/Creating-Stability.gif" alt="" /><img hspace="5" height="160" width="200" vspace="5" align="left" src="/sites/default/files/Providing-Expertise.gif" alt="" /></p>
<p><img hspace="5" height="160" width="200" vspace="5" align="left" src="/sites/default/files/Leading-the-Field.gif" alt="" /><img hspace="5" height="160" width="200" vspace="5" align="left" src="/sites/default/files/Changing-Policy.gif" alt="" /></p>

Also, if I want to place a vertical image to the right of those four boxes, how could I do that?

Thanks very much.
