The easiest way to do it would involve the use of the position property. Change your CSS to this:

div.header {
	position: relative;
	height: 100px;
	background: url(...header_bg.gif);
}
div.header h1 {
	display: none;
}
div.header img {
	float: right;
	margin: 0;
}
div.header a {
	position: absolute;
	top: 75px; /*Change this value*/
	left: 10px; /*Change this value*/
	float: left;
	margin: 0 0 25px;
}
