I satisfy that by never overwriting the older package with the new; I  
always setup a fresh new directory but copy the settings.php files I  
need from old to new.  Run update.php only on the Drupal core first.   
Add the modules I need and execute update.php for the modules.  This  
method will always deactivate any modules since they do not exist for  
the first update; Drupal core is smart enough to deactivate them for  
you.

I use symlinks as well.  My directory structure is  
/opt/drupal/drupal5/drupal-5.1, /opt/drupal/drupal6/drupal-6.1, etc.   
I also move the first instance of the sites directory to  
/opt/drupal/drupal[56] and symlink the sites directory, e.g. ln -s  
/opt/drupal/drupal6/sites /opt/drupal/drupal6/drupal-6.1/sites.  This  
way upgrading each release of drupal6 becomes easier.

The difference here is that I don't modify .htaccess as you have.  But  
that could be a requirement of your environment.

Well I would make sure to follow each modules instructions.  Certainly  
deleting files that have been uploaded or needed for the site to work  
isn't desirable.  I remember that I had an issue the first time I  
tried to update from 5 to 6.  But then I decided to, first upgrade to  
the latest 5.x version.  Upgrade to version 6 without contrib modules  
installed.  Then install contrib modules and upgrade.  These actions  
produced a working application.  I don't remember if I noticed any  
errors from the update.php but it seems maybe there were some for a  
few modules.

You need to upgrade to the latest version of 5.x because the updates  
are not carried from version 5 to version 6.  Perhaps that is the step  
you need to take.
