Installing Drupal

I'm new to all of this and don't really know what I'm doing. I unzipped the files and uploaded them to mydomain.com/drupal. However, I get the error "Warning: mysql_connect(): Access denied for user: 'drupal@localhost' (Using password: YES) in /home/alforish/public_html/drupal/includes/database.mysql.inc on line 12
Access denied for user: 'drupal@localhost' (Using password: YES)"
I set up a mysql account for user drupal, but it created it as mydomain_drupal instead of just drupal. Is this what is going wrong? How can I fix this?

Hello,
I managed to install drupal and everything is working fine so far. THANKS for the great work !!

However, the first problem I stumbled upon has to do with commenting. I created two accounts, the admin and a user. Logged in as the user, I wrote a blog entry. When I try to comment that as admin, I get the following error notice:

---
Fatal error: Call to undefined function: comment_moderation() in /path/to/server/public_html/themes/goofy/goofy.theme on line 145

I am running drupal 4.2 under iis and php4.3.1. When I click on edit links in the header I get a 500 internal server error. I have checked and magic quotes is off. Any suggestions as to how I can correct this. I want to have links as per marvin, or as per drupal.org.

How can one go about changing the link colors to the new menu system with drupal 4.3-cvs. I've spent hours looking and experimenting with it to no avail. Could someone shed some light?

I have been trying to place a Flash movie (analog clock) in a block for display. The block is recognised but the flash movie does not appear to load. I think it may be in the pathing but have not been able to get it to display. Any comments most appreciated.

How can I get rid of the escape characters that are automatically inserted into my posts? All my contractions are ugly. :) I'm becomes I\'m...

In my DB coding, this is always something I have had to do in code... is there a drupal module that takes care of it? If not I imagine there's a php configuration option... anyone know what it is?

Any help would be much appreciated. TIA.
