Upgrading Drupal

I want to upgrade from 4.6.4 to 4.6.6
do I need to upgrade to 4.6.5 first and then to 4.6.6?
I read that I don't have to do a dbs upgrade?

I followed all the instructions in upgrade.txt to upgrade to drupal 4.7 beta 6. After this, my theme was lost, and the admin and node folders are missing. When I click on administer, I get a 404 error, smae with my nodes. I have php5. What did I do wrong?

Having upgraded to 4.6.6, everything is finally working, that is until nervously opening the page in Internet Explorer.

Surprisingly the only thing, apart from mangling my 'nice menus,' it will not let you login. This is troubling. My site is www.almamata.net/news

Has anyone had the same problem, or have suggestions? I know IE is a pain in the proverbial, but have users in places where it's likely to be used a lot.

much appreciated

On upgrade to 4.6.6. I have found that my cron has stopped working. I can still get cron to run if I run it from the browser bar at http://kiloalphatango.com/cron.php but my scheduled crontab is no longer working. I have not changed the crontab file.
