Lab Rats Rule

Ah yes, was wanting this.

Here's one:
 

I'm going to need ACP access to help you out with this one.

@Martin A.  thank you for your help.  You are awesome!  

Well, I had already tried the code the way you posted, and it was still skewed.  And nothing was centered also.
But wait a minute....  When I use your center code for the ad, my having the ad code above <div id="ipsLayout_mainArea"> works.  And the map is fine,
Although now I am starting to like the ad placed between the block and left margin where there is a side block now (centered elsewhere).  But that won't work because  IPS won't fix that.
Wow you really know your stuff.

Great, thank you for your quick answers !!

And you know what else?  I forgot to mention this.  After I posted screen shots showing the admins session frozen from when they worked on my site on Tues, I got the famous, blame the server business.  And BTW, I had zero issues with this prior.  What do they think we are, idiots that will fall for anything?
.But just this once they didn't try to sell me hosting after they mentioned my "ailing" server.  Whoopie!  Anymore I feel like I am working with snake oil salesmen that will tell your anything,
 

Fairly soon, I want to push out another 'beta' release when I've finished the interface for adding member markers.
