Post installation

I'm using Drupal 4.7, I'm working on hosting multiple sites. So far my sites folder looks like:

sites/default/settings.php
sites/x.x.com/settings.php

1. I want to know do I need to rename the default directory to "x.com".
2. What do I set the apache Virtual host document root to in the server config?
Thanks in advance,
Ben.

First of all, I'm having touble making categories in my new drupal instalation at www.beachespanama.com/drupal. Basically what I want to know is, how would I make a category named www.beachespanama.com/drupal/Beach_Directory, and then in that link have all the info for that section.

OK, I'm getting a bizarre problem with a site I'm working on. http://www.highstatusdater.com. I stopped working on it last night, and everything was working fine. When I woke up this morning and tried to look at the site, it's now not working, and is giving me a popup asking if I want to open or save the file. This is a similar problem to

http://drupal.org/node/42051

is there a way to remove the login things from my site view? i dont want other people to see the login thing but would also be able to login.. is there a way to do this? thanks

Does anyone bother with customization of event module?
I want, in the event box, to have category instead of content-type.

To be accurate:

instead of:

Upcoming events
-some event
(%count days) (content-type)

I want:

Upcoming events
-some event
(%count days) (category)

please help

All I want is an alternative to flexinode (or having to build one's own node type using story module as the basis) that will have title, body and image fields and working teasers and node views. I guess the image field is still being worked upon, so can I put the image in the body field using img_assist and will it work?
