fedora teething problems

Hi, recently got fedora on my pc - very good. Well done whoever makes it! Few probs to solve though...if anyone knows the answer pls help me... 1. I get my ip address dynamically, so my /etc/hosts file is empty - but fedora complains about this on start up. What should go in there...? just my hostname? hostname and any old address? 2. The bottom of a Mozilla browser is covered by the start bar. How can I make it open so it fits within the window space? (It is impossible to size it down by hand because you can't get hold of the bottom of it). 3. And if you are still reading...the auto-update ia great for fedora packages etc, but what abput something like Ogle dvd player. As yet, I have had to search for the rpm, then look for its dependencies... and so on. Surely this is not the way to do it? surely it can be done automatically?
