Develop a simple FB application, getting errors???

Hi,

I am testing with the developing of a FB application, at the moment just a very simple image with some hotspots.

I have this in mydomain.com/facebook/index.php

 <a name="fb_share" type="button" href="http://www.facebook.com/sharer.php">Share</a><script src="http://static.ak.fbcdn.net/connect.php/js/FB.Share" type="text/javascript"></script>
   <img src="http://www.mydomain.com/facebook/imgs/facebook-test.jpg"  width="518" height="900" border="0" usemap="#Map" />
     <map name="Map" id="Map">
       <area shape="rect" coords="404,585,517,657" href="http://www.digitalpoint.com" target="_blank" />
       <area shape="rect" coords="405,335,517,430" href="http://www.cnn.com" />
     </map>

Code (markup):

And i turned it into a application (iframe) so i can add it as a tab.
But i am getting the following errors:

Application temporarily unavailable
Parse errors:

FBML Error (line 23): illegal tag "map" under "fb:tab-position"

FBML Error (line 24): illegal tag "area" under "fb:tab-position"

FBML Error (line 25): illegal tag "area" under "fb:tab-position"

Runtime errors:

Names beginning with "fb" are reserved by Facebook (fb_share)

Cannot allow external script

Code (markup):

1/ So i guess FB parse the html content in the iframe and strips out certain tags???
2/ How can i make simple image hotspots work? And where can i find a good tutorial on developing a dynamic application, say a form which interacts with a db on my server???
3/ What is exactly the difference between creating a page vs applications?

Regards
