Post installation

I tried to upgrade the gallery2 mod on the downloads page to the new beta upgrade. I couldn't get it configured right, so I tried to go back to the other one. I copied the exact code from my backup gallery.module file and pasted it in. It works but if I enable the random image block, I get a php error:

warning: Illegal offset type in /home/.../.../drupal-4.6.3/modules/gallery.module on line 202.
I also get a css error that it can't find my theme's css file

I want to upload my own logo ( or at least set the path to it) but there is a line above the fields that says "The directory files is not writable." How do I change that? Sorry that I am asking so many questions, I am new at this.

How do I fix the following?

1. warning: mkdir(): SAFE MODE Restriction in effect. The script whose uid is 550 is not allowed to access /tmp owned by uid 0 in /home/virtual/site39/fst/var/www/html/articlemanager/includes/file.inc on line 86.

This shows when I clicked on the settings link inside the administer category.

2. When ever I submit something (stories, settings, etc...) THe theme is lost do to the fact that the url shows up as:

Whenever I click on a link the url comes up as:
http://www.webreality.net/articlemanager/webreality.net/?q=admin/comment

when I take out webreality.net before ?q=admin/comment the theme shows correctly. Otherwise it shows no theme. How can I fix this problem?

I have installed the CAPTCHA module on my 4.6.0 drupal. I installed the comment.module patch. The only patch that seemed to work for me was comment.module_9.patch. Everything worked, users were able to comment using the CAPTCHA. Now the CAPTCHA doesn't show up anymore. I have tried all the other patches and still doesn't even appear. My board is being spammed heavily.

comment.module: v. 1.347.2.2
captcha.module: v. 1.15
