Look this plugin:
http://jquery.malsup.com/form/

Read about ajax submit.

For jquery ui datepicker you can "ignore" the datepicker form..
IE:

<form>
  <input 1...>
  <input 2....>
  <input class="datepicker">
</form>

Lets see the js code:

$(".datepicker").datepicker();
$("form :input:not(.datepicker)").tooltip();

Now you have the datepicker of jquery ui and the tooltip on same form.
