Upgrading Drupal

I currently have nodequeue version 5.x-1.2 installed and need to upgrade to the latest version that is discussed on: http://drupal.org/node/205435.

I found documentation on installing a patch but cannot find documentation on upgrading to new module releases. How would I upgrade to the latest release?

I have a drupal 5.x installation on http://www.vshiksha.com . Will it be possible for me to port it to Drupal 6.x?

After upgrade, which apparently went well, any change to the profile field values is not written back to the database. Anyone know why?

I'm upgrading from 4.7 to 5.6 - and everything is going remarkable well. except ....
I've got two CCK content types, both with a simple text field, both with custom contemplate templates (but are very similar)

One of them displays just fine...

The other will not display the text field in either in the full node or in the teaser view.
The data is in the database.
I've tried resetting the template - but it still does not show up.

Ok, so I upgraded my site from 5.5 to 5.6 - Followed the upgrade.txt file from 1 to 10. All was good and got to the upgrade.php part (database upgrade). And that ran with no errors at all. Nice, right? Well, not so fast!

While i was checking to make sure all is good, i noticed that some and not all articles don't show the teaser or the body when you click on the actual article. So, I will have an article title but no body what so ever!

I can't configure any input format in any of my sites. I need to reconfigure allowed html tags, but when I clic on "save configuration" nothing happens.

Please, help.
