Editing the HTML code of my home page

I am using the Elegant Theme SimplePress. For some reason, it seems that the theme added 2 nested div blocks in the content area below the slider which forces the content to be pushed to the right and outside of the borders of the content area. I have no idea how to get rid of those divs because I don’t know how to access the html of that page. So this is what I did:

I opened that page in my browser and chose, View Page Source. I copied all of the html and pasted it into a new document in Dreamweaver. The code that contains the mystery divs must be somewhere in here:

<div class="wrapper">
    <div id="blurbs">
				                <div >
            <span class="titles">About Me</span>
            <div class="jqDnR" id="idTextPanel">A wonderful serenity has taken possession of my entire soul, like these sweet mornings of spring which I enjoy with my whole heart. I am alone, and feel the charm of existence in this spot, which was created for the bliss of souls like mine. I am so happy, my dear friend, so absorbed in the exquisite sense of mere tranquil existence, that I neglect my talents. I should be incapable of drawing a single stroke at the present moment; and yet I feel that I never was a greater artist than now. </div>
            <br class="clear" />
            <span class="readmore"><a href="https://makeyourpassionworkforyou.com/about-me">read more</a></span>
        </div>
        				                <div >
            <span class="titles">Contact Me</span>
            <div class="jqDnR" id="idTextPanel">A wonderful serenity has taken possession of my entire soul, like these sweet mornings of spring which I enjoy with my whole heart.

        </div>
        				                <div >
            <span class="titles">Some Inspiration</span>
            <div class="jqDnR" id="idTextPanel">
<div class="jqDnR" id="idTextPanel">Far far away, behind the word mountains, far from the countries Vokalia and Consonantia, there live the blind texts. Separated they live in Bookmarksgrove right at the coast of the Semantics, a large language ocean. A small river named Duden flows by their place and supplies it with the necessary regelialia. It is a paradisematic country, in which roasted parts of sentences fly into your mouth. Even the all-powerful Pointing has no control about the blind texts it is an almost unorthographic life </div>

        </div>

        <br class="clear" />
    </div>
    <span class="blurbs_shadow"></span>
</div>
<br class="clear" />

Question 1:
Where are those divs in this code that I must remove?

Question 2:
When I remove those divs, which document is this in my template so I know what to save it as and upload it back to my site via an FTP server?

Question 3:
Am I doing this right? Is there a better way?
