O.K...
Are you wanting to MAKE Linux look like like a MAC or something that is just Graphical in general with all the pretty colors etc?. Most Linux distros will allow you to do this with some configuration. Distros like SUSE have a graphical interface/desktop by defult, so you don't need to do much configuration. their are also other Distros out there like this like Sabiyon, PCLinuxOS etc
As for Burning Software and other Apps you use things like K3b or Gnomebaker for burning as for other apps it is really about finding alternative programs you are confortable using. Alot of this has to do with the choice of distro as well..
Gaming in Linux is getting better but still not as good as Windows but here is a list of games that are native to Linux:

As for a firewall/Antivirus software for Linux there are Linux firewalls/ Antivirus Software available but it is really not necessary
you can use WINE or Cadeda for games, I don't know about this The General will be able to help you more with this
Fedora is just another Version of Linux there are now over 200 Linux Distros available. there is really no difference some distros may be more graphical more advaced than others but really all Linux distros are the same under the hood it is all about which distro you are comfortable using.
To this end I recommend trying a few live Cd's first. Live Cd's are Distros that run entirely from CD ROM and don't touch your HDD. This is a great way to test out Linux distro without the risk
here are a few personal recommendations:
Kubuntu

PCLinuxOS .92

ftp://ftp.nluug.nl/pub/metalab/distributions/texstar/pclinuxos/live-cd/english/preview/
This is the distro I use and recommend, Why because it works right out of the box. No need to configure Everything, everything just works. It also comes as a 1 CD install that is a live CD that you can install later if you wish.
