Rails 3 + passenger conf file - ruby-on-rails

Question

I have been trying to install a rails app on a box that originally was used for multiple php applications. I installed passenger and created a conf file but I am confused about how it all works together.
What should my ServerName be if i want to access a Rails app? The box is a debian squeeze running apache2 with passenger module installed. Below is my conf file. I currently have to go to xxx.xxx.xxx.xxx/leoadmin/public to get the application to run properly. I have the following htaccess in the public directory. Which I think is unnecessary if my conf file is configured correctly.
I think my main issue is the misconfiguration of the conf file. I believe the conf file is being loaded but i don't understand why i still need the htaccess for me to see any action.
.htaccess
#PassengerEnabled On
PassengerAppRoot /var/www/leoadmin/
#Options -MultiViews
#PassengerResolveSymlinksInDocumentRoot on
#Set this to whatever environment you'll be running in
RailsEnv production
#RackBaseURI /var/www/leoadmin
vhost config
<VirtualHost *>
ServerName leoadmin
DocumentRoot /var/www/leoadmin/public
<Directory /var/www/leoadmin/public>
Allow from all
</Directory>
Alias /leoadmin /var/www/leoadmin/public
<Location /leoadmin>
SetEnv RAILS_RELATIVE_URL_ROOT "/leoadmin"
PassengerAppRoot /var/www/leoadmin
</Location>
ErrorLog /var/log/apache2/leoadmin-error.log
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warn
CustomLog /var/log/apache2/leoadmin-access.log combined
</VirtualHost>

I had nothing but pain and more pain trying to get this sorted a few months back, my configuration allows me to do sub URIs, so I'm not sure if that's what you want, but it'll be along these lines. I've never needed a .htaccess file for this setup:
NameVirtualHost *:80 <VirtualHost *:80>
ServerName www.test.co.uk
DocumentRoot /web/rails
<Directory /web/rails>
Allow from all
</Directory>
RailsBaseURI /test
RailsEnv development
<Directory /web/rails_projects/test/>
Options -MultiViews
</Directory>
For me /web/rails is a root directory, from there I have a number of symlinks to my /home/ directory where I store my projects. ServerName is whatever qualified name you're using for the machine that's going to be recognised.
(just in case, I'm running Passenger 3.0.9, and Rails 3.2.11)
