Answer 1

There's an alternative to AJAX!

You can load ALL three possible contents into separate DIVs.

Then clicking on a tab will simply make the display attribute of the appropriate content's DIV "block" while making the other two DIVs' display property "none".

Cheap, easy, does not require AJAX costs for extra http request or for coding.

Mind you, AJAX is a better solution if the contents of the tabs will change dynamically based on other data as opposed to being known at the time the page loads.
