Vbulletin CMS 4.0 homepage url

When I go to my main url for my site using vbulletin cms homepage for domain: Radar-Detector.net it automatically rewrites and goes to Radar-Detector.net/content.php ....

for google ranking I am thinking the /content.php wouldnt help at all? How would I get rid of that extension and just have the normal url Radar-Detector.net instead?

I want to have my main landing page (cms page) to be the main url Radar-Detector.Net how do I change this?

Also I was looking in my main root the .htaccess file and here is the code below, do I need to change these fields or does vbseo already take care of it?

# Comment the following line (add '#' at the beginning)
# to disable mod_rewrite functions.
# Please note: you still need to disable the hack in
# the vBSEO control panel to stop url rewrites.
RewriteEngine On

# Some servers require the Rewritebase directive to be
# enabled (remove '#' at the beginning to activate)
# Please note: when enabled, you must include the path
# to your root vB folder (i.e. RewriteBase /forums/)
#RewriteBase /

#RewriteCond %{HTTP_HOST} !^www\.yourdomain\.com
#RewriteRule (.*) http://www.yourdomain.com/forums/$1 [L,R=301]

RewriteRule ^((urllist|sitemap_).*\.(xml|txt)(\.gz)?)$ vbseo_sitemap/vbseo_getsitemap.php?sitemap=$1 [L]

RewriteCond %{REQUEST_URI} !(admincp/|modcp/|cron|vbseo_sitemap)
RewriteRule ^((archive/)?(.*\.php(/.*)?))$ vbseo.php [L,QSA]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !/(admincp|modcp|clientscript|cpstyles|images)/
RewriteRule ^(.+)$ vbseo.php [L,QSA]

This feature will be fully supported on vBSEO 3.5.0 Gold

I hope blogs will be too.
eg. site.com/blogs instead of site.com/forums/blogs. The current way it is done is not ideal.

Yes, blog custom URL will also be a supported feature not yet implemented in RC1
