Upgrading Drupal

Hello Dudes!

Im a new user with this software, but usually i solve problems
by reading forum posts.
not this time :(

while upgrading TinyMCE, i get this error message:

An error occurred. http://horst-sergio.net/drupal/update.php?id=5&op=do
Fatal error: Call to undefined function _system_update_utf8() in /home1/xxxxxxxx/public_html/drupal/modules/tinymce/tinymce.install on line 24

I know how to write simple SQL commands, but I do not know how to translate a Drupal6 hook_schema function into an SQL command. I need to do so because i18nstrings.install is for some reason not creating its table in the database. Can someone tell me how to translate this function into a command I can run directly in phpMyAdmin?

Generally this is what I always do when my status report tells me that there are newer versions of modules available:

1 - Site maintenance mode
2 - Backup site and database
3 - Remove - rm -fr xxxxxx modules from my modules directory
4 - Download and then unpack the newer versions into the modules directory
5 - Run update.php

How do you know when you have to run update.php though? I notice sometimes that it says no database updates are required after I update my modules.

I just upgraded to Drupal 6.4 and now site content isn't available to anonymous users.
The only available buttons are Forum and Home - the rest aren't visible.
Anu odeas what could cause this?
Thanks,

is there any way to monitor when is the appropriate time to simultaneously upgrade rc versions of interdependent modules?

for example say you have

moduleAversion1+moduleBversion2 = ok

if you upgrade to moduleAversion2 = problem

but if you upgraded to moduleAversion2+moduleBversion6 = it would be ok

how are you supposed to figure out which versions work with each other?

maybe it's smartest just to wait for major releases?

As part of the upgrade process I renamed my old modules folder to _modules and then copied it into the modules folder, to make it easy to transfer my custom modules to /modules in my FTP program.

But now when I try to delete /modules/_modules, I get a white screen. But if I leave the _modules folder alone, I get these errors on the admin side:
