Answer 2

I found that learning how to do a child theme using thematic to be really quite awesome.

Here is my post, with tips inside for those just starting out. I give an example in there that looks like this:

<?php
  function calltoaction() {
     include(STYLESHEETPATH . '/calltoaction.php' );
  }
  add_action('thematic_navigation_below', 'calltoaction', 1);
?>

And thematic has great support on the themeshaper forums.

Answer 3

I'd go with Thesis because you can just do a lot of stuff in the admin section and if you need to go further, is not hard to find snippets of code to paste on the custom_functions file
