you should figure out if the version of Drupal you are using is
compatible with PHP 5.4 (used by Fedora 18)

webrick is only for development mode - not suitable for actually running
an application as it's single threaded.

CentOS does not differentiate server/workstation but only installs
CentOS and the packages you choose to install essentially determine what
the role will be. Throughout the life of say CentOS 6.x, it won't change
much at all - only bug fixes, security updates. Versions of server
daemons rarely change. Sometimes the versions of desktop applications
change but that is still infrequent and typically done out of necessity
(ie, when Firefox obsoleted earlier versions).

not actually true

2 GB RAM is not all that much for a desktop system.

top?  ps?

highly unlikely to ever happen. Rails developers are in demand and
always busy if they are any good. Railstutorial.org is where you should
focus. Also, there are some very good books but dead tree versions are
always out of date.
