Drupal 6.x

Hi,
I'm working for implementation of complicated analysis of a results of psychological tests of users
for a Drupal-based web site.

I have a skill in programming, but I would like to modify built-in solution,
instead of writing additional module.

Therefore, the question is:

Are there any existing modules (additions, etc.) for Drupal, which could be used
for creating user interface for psychological testing with automatical storing their results in database?

Thank you.

I am a huge naruto fan (Biggest Hinata fan ever thank u very much) and I used to watch all my episodes on http://tailedfox.com UNTIL today. Today I was gonna get on the site and watch some old eps when SUDDENLY a Drupal no-access page came up! IT WAS THIS: user warning: Can't create/write to file '/tmp/#sql_2520_0.MYD' (Errcode: 17) query: SELECT DISTINCT(p.perm) FROM role r INNER JOIN permission p ON p.rid = r.rid WHERE r.rid IN (1) in /home/naruto/public_html/includes/database.mysql.inc on line 172.

It seems there have been some changes to the way taxonomy works, but I can't find any documentation of it. Does anyone know where we can find details?

I am working with someone who is looking for to launch a tours travel website I have been looking for the best solutions since we want to be able to implement airline tickets booking couple years from now. I am totally new to Drupal but heard all the good things about it. Is it a good choice?
Also, how come there are so many active versions of Drupal?

Specs:

Thought that I might help development of Drupal 6 by installing the beta, but have already run into a fundamental problem.

Ftp'd files and ran installation script, granting access as stated in the Install.txt file
(ie GRANT WRITE PERMISSIONS ON CONFIGURATION FILE)

Once I ran script it I was directed to "Administer" page where I was told to make permissions on sites/default directory secure, did this and got taken back to the install.php script again.

Seem to be stuck in a loop....can anyone help?
