Adding Adsense to Theme

I want to add Adsense to some templates so I have:

1.) Link unit across the top of each page
2.) Sidebar
3.) Rectangle ad block floating on the left, inside the content, on the first post on every page.

I got #2 done.

I found this link from searching the forum http://www.tamba2.org.uk/wordpress/adsense/ -- It has help for #1, but it doesn't tell you which file to edit.

Still haven't found a way to do #3

Can anyone help me or point me to a good, easy-to-understand guide on getting #1 and #3 done?

I recommend you stick to 2 ads. 1 directly above the content and below the header, and a second one on the sidebar blended to make it look like menu links.

Getting it into the post itself is not easy. I have no idea how to pull it off.

In your theme template file "single.php", just before the call "the_content()" you would add the adsense code wrapped in a <div style="float: left;"></div>

That should drop it right in...

Thanks guys, will give this info a spin
