H1 Logo in body not working correctly - php

Question

I am by far not an expert with PHP, and could really use some help creating my logo below into a H1. This is in my body section of the site:
<!--logo-->
<div class="logo" style="float:left;">
<?php echo $html->link($html->image('rental_logo.png'),array('controller'=>'homes','action'=>'index'),array('escape'=>false)); ?>
</div>
<div class="logo" style="float: right; margin-right: 470px; padding-top: 40px;">
Here is what I tried to create the above logo into a H1 tag:
<h1>
<a href="<?php echo $html->link($html->image('rental_logonew.png')?>" title="http://example.net/img/rental_logo.png"><br/>
<img src="<?php (http://example.net/img/rental_logonew.png);>/images/rental_logo.png" alt="vacation rentals" title="logo"
</h1>
I am very inexperienced writing code. So, I know the above that I tried to enter is wrong. Should I also be altering my look.css file?
/* css */
#logo {
background: transparent url("http://example.net/img/rental_logo.png") no-repeat scroll 0% 0%;
float: left;
/*width: 200px;*/
padding-bottom:10px;
text-indent: -3333px;
border: 0;
margin: 0;
}
#logo a {
display: block;
width: 280px; /* larger than actual image? */
height: 120px;
text-decoration: none;
border: 0;
}
I am attempting to add "rendered html" as requested. This may be incorrect, because I am unfamiliar with rendered html. I obtained the above codes from my header.ctp and look.css files.
($html->image('rental_logonew.png'),array('controller'=>'homes','action'=>'index'),array('escape'=>false)); ?>
Thanks for looking, and helping if you can.

In the php code i dont see where you close the "a" tag, just follow the structure bellow. I hope it will work.
CSS:
#logo {
width: 344px;
height: 82px;
margin-top: 10px;
/*float: left;*/
background: url(../images/logo.png) no-repeat;
}
h1.logo {
width:344px;
height:82px;
margin:0;
padding:0;
}
h1.logo a {
display: block;
height: 82px;
text-indent: -3000em;
overflow: hidden;
}
HTML:
<div id="logo"><h1 class="logo" title="logo"><a title="logo" href="/">Logo</a></h1></div>
