Well done, that's a triumph for you. I'd not come across that particular configuration option. I shall make a note of it for future reference.
As to installing software. Most distributions maintain repositories of software that for one reason or the other is not included in the install and it is always best to get software from there if it is available. That way it has been compiled with the best possible chance of working on your system.
Fedora slightly complicates the issue as it has very strong views about what should be included in their official repositories and so it has a series of third party repositories that are more loosely linked to the main one. A word of warning, only install from one of the third party repos until you have experience of what you should and should not do.
Installing software in Fedora can be as simple as issuing the command:
That will install a rather nice graphical package manager called yumex and put an entry in your menu system
This howto contains instructions for installing almost everything else you would need in Fedora8 and I commend it to you.
Near the top it tells how to set up for Livna for instance which is the most used third party repo.
Best to work through that howto and then post back on individual problems.
