Upgrading Drupal

Hello,

I have installed drupal 4.5.5 in a linux server with debian testing, I have installed the debian package version 4.5.5-1. I don't realized earlier, but I think since I have upgraded to this version due to a security problem I can't publish articles from external programs like w.bloggar, blogjet or blogtk. Before this I can publish. The error in each program is:

I have some trouble with pictures disappearing. I am using Image, Image_Assist and Pathauto Modules.
After I moved a document in the book hierarchy, all images disappeared. Now I only see a link to the large image but not the thumbnail preview.
When I go to Edit, I can see the pictures in TinyMCE. After submission i still don't see them.
Every time i change something, (e.g. settings in the Image Module or adding some text) all images will disappear again.
Did anyone encounter a similar issue?

I have the strangest problem... it only happened on one site i attempted to upgrade to the 4.7-cvs version of drupal, and not on another... This site had lots of nodes,

On the "node/add/story" page, or any other content type EXCEPT flexinodes, the Title field is marked with an error, and it says "You must enter a title".
On "node/add/flexinode-1" or any flexinode, it displays NO TITLE FIELD at all.

Has anyone else had this situation?

When running update.php, how does one correctly determine which item to pick from "Perform updates from:" menu?

My concerns are:

* It states, "This defaults to the first available update since the last update you performed." However for me the default was several months prior to the release date of the last update I ran, which I gathered from looking at my previous CHANGELOG.txt file. Can I trust this? When I run the default item there are a lot of errors.

Short question: How do i import a sql backup into an existing drupal database?

Background
I want to back up my site to another server both because i need to upgrade the site to 4.6.3 from 4.6 and because i want to use the skeleton I have developed for my first site for another project and much of the work is recorded in the database--not the drupal files (except for the theme development). I don't know much about command line interfaces and type commands very poorly so i am using cpanel, fantastico and phpmyadmin.

Both servers provide a fantastico script that will install a new drupal installation with two clicks and which sets up the basic drupal database.

My plan is
1. set up a clean 4.6.3 install of drupal with no modules at backup site
2. export the original site using the export function in phpmyadmin
3. import the resulting sql file into the backup database
4. copy the drupal files (modules, themes, files etc) into the backup
5. Not delete the settings file in the backup site so that it continues to point to the backup database not the original one
6. upgrade from 4.6 to 4.6.3 on original site.

My thinking is that i will be left with a verified back up, a clone ready for divergent development, and two upgraded sites.

my problems
--I don't know how to import the resulting 2.3 mb file into the back up database using phpmyadmin
--i don't know if this procedure will result in valid functioning of the modules in cases where a trable was created in the dbase.

I upgraded from 4.52 to 4.6.2, and then to 4.6.3. I am using a tweeked version of the marvin_2k_phptemplate template.

When an anonymous user attempts to view content, nothing is displayed. The front page shows the "welcome to drupal... new installation... etc. etc." message, and when the anonymous user attempts to view forums, they see no messages, no views, nada.

I checked my permissions and all is well. Anonymous users are allowed to access content.

My other website does not have this problem at all.

Is there something I can do to fix this?
