Why switch the firewall off? I haven't used Fedora in some time, but I have some suggestions:
  • Log out of your Gnome desktop, and don't drop to runlevel 3. That way your Gnome desktop isn't locked up.
  • Add the ports that VNC uses to your list of allowed ports in the firewall. That way, you don't ever have to worry about it again. VNC display number 0 is port 5900, display 1 is 5901, etc.

One of the things you could try is running redhat-config-securitylevel in the GUI, and just disable your firewall. If you don't have any vital services running, then you don't have to really worry about the security implications of not having a firewall. I personally barely have a firewall, if you could say that. But, I get by because my gateway server has every port closed except for SSH and FTP, and I've set up access control lists on both services, only giving access to clients I've pre-approved to connect to me.

So, I don't have a firewall doing much, but that's because I made sure to cut out unneccesary services. For instance, do you need apache running on your box? What about portmapper? Don't have any NFS shares? You can cut those out. I usually port scan my box every now and then, just to see what ports are open, then I determine if I really need any of the services that are running.
