Drupal 4.5.x or older

I am very confused and very frustrated. I got the new version of Drupal, have it installed on my server and all is well. Now, I have no idea what I'm doing. I'll break this down as simple as possible and if anyone can help I'd appreciate it.

I have a site now that hosts online automotive learning groups. Each group is themed and is moderated by an expert in the theme of the group. For example there is a Honda Learning Group, a Hybrid Learning Group, etc. You can view the site at http://www.autotech-elearning.com/forum/fusionbb.php

Each learning group needs its own forum, articles section, bookmark/directory, etc.

Can I do this with Drupal?

Thanks in advance for your help on this question!

A complete N00B here. I am using a discussion forum type software now, but I need some of the additional features like are offered by Drupal (authoring, bookmarks etc)

The main think I have to be able to do is to control forum access via subscription. With Drupal will I be able to use a group permissions scheme to control access to forums based on a person's subscriptions.

hello guys,I need your help, PLEASE,
I've got my web site,which is not ready yet, and as I assume won't be ready soon, that's the adress: http://webbiz2.com/HOME.htm ,
anyway what I need is to implent a CMS system into some of my web pages.
Can I use my own layout? without original one?
I wish I could work it that way:

I have moved my site (drupal 4.5.7) to the new server and now I have this errors in watchdog:

strict warning: date() [function.date]: It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Europe/Berlin' for 'CEST/2.0/DST' instead in /home/www/modules/node.module on line 1018.
