“fixedDataDropdown”, “dependantDropdown “, “uBrowser” or “Active Select” Sub Taxonomies help!!!!

Ladies, Gentlemen, fellow geeks and Drupalites…
I come looking for your assistance. I am bringing my little site http://afterthemouse.com over to Drupal from a hand crafted PHP solution and my issue is the communities. Previously I used this bad boy of a form http://mouse.nodstrum.com/form2.php to collect some of the data but now I am trying to be a little more precise.

Here is what I am trying to do, my site is a reunion/community site for ex-Disney Employees like myself… The community as a whole can, and I thing should be broken down into smaller, more searchable groups based on work location, have a look at this screen print for an idea of the scale of what I am talking about… http://flickr.com/photo_zoom.gne?id=139614132...

So I was thinking about something like “fixedDataDropdown”, “dependantDropdown “, “uBrowser” or “Active Select” plugins. BUT really I would like to further complicate this with two more things. Firstly being able to select the dates that the members worked in each area, and secondly being able to add multiple work locations as most of us worked around the resorts.

Any ideas on where to start?
