#widgets {
	background: none;
	left: 620px;
	position: absolute;
	top: 30px;
	width: 250px;
}

Note that if you move them to the left, there may be some funny overlap with the site title. You would either need to fix the widgets in place like the site title and keep them small enough to still work for people with smaller screen sizes or you could make it so the site title area scrolls.

Regarding the footer, we do require that you keep the footer credit links in place. You can adjust the appearance so they don't stand out as much though. Here is an example for your blog:

#credit {
	width: 280px;
	font-size: 1.05em;
}
#credit a {
	color: #777;
}
