I upgraded from the grandfathered Advanced to Extra Class about two weeks back.

In case you haven't tried it go to http://www.qrz.com
when you get your call and register on the site. They have great practice tests from the questions sets and keeps track of your score as you improve.
Also try www.w5yi.org
and order the Gordon West study books. He really makes General and Extra Class tech material easier to understand.
