I can honestly say stay away from dedicated servers if you have no experience with them! Your best bet would be to stick with your reseller. Now you could prepare yourself by stoping over at the fedora download site (http://fedora.redhat.com/download/) and grabing yourself a copy of fedora.... then install it on a partiton of your machine! Play with it (CONSOLE ONLY) until you learn it like the back of you hand! If you have the extra money you could even pick up a VDS (Virtual Dedicated Server)
