I've done some further research on the subject and thought I would share my findings with the forum.
Here are useful notes that I've taken from various sources on how to host/deploy your RoR applicationL

2. Install software on server *installation guides http://rubyonrails.org/download*

3. Webservers - Apache, Nginx, Lighttpd, -- Passenger/ Mod_rails, Mongrel, Thin, Unicorn.
-Recommended Apache + Passenger .
4. Deployment tools.

Hope that helps a bit.
