I installed drupal on my home system first, so I could learn it before, putting it up at the hosting site and everything went perfectly.

Unfortunately there was a few things I didn't consider and the hosting installation created a few questions.

How do I make files secure and writable by drupal?

It's currently:
files Myusername Mygroup rwXrwsr-X

I can't change it to the Apache servers group and making other rwX seems like a bad idea on a hosted site.

conf.php

Is world readable, security problem again since it contains the mysql password.

If I enable most modules, Drupal 4.5.0-rc1 uses to much memory and hit 8MB memory limit of the hosting site. I haven't run rc1 at home yet, so not sure if it's a hosting site issue or rc1 issue. Isn't 8MB default memory limit?

Even when I enable the linebreak enhancement, it still makes everything I type one line in the restricted HTML mode (Full HTML works). Looking at the formatting guidelines when typing this, I can see they contain
and

, but those is not configured in rc1 out of the box. It was in fact rc1's default Allowed HTML tags that doesn't allow for the auto linebreaker to work, updating to use the Allowed HTML tags from drupal.org fixed it.

"The configuration options have been saved." this line is ontop of every page I view, doesn't matter if it's in configuration or elsewhere, it's a parment part of pages now.
