e.g. GIMP? Emacs? Is there a music program based on the same model.

I REALLY NEED HELP WITH LINUX!!?

In order for me to do something like listen to music, videos, etc it tells me that I have to download Adobe Flash Player. It gives me these choices:
YUM for linux
.tar.gz for linux
.rpm for linux
.deb for ubuntu 8.04+

I tried all of them and nothing. I did use the terminal and it tells me:
Reading package lists… Done
Building dependency tree
Reading state information… Done
flashplugin-nonfree is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

-What am I doing wrong?! When I tried going to the sites it tells me that I have to download the A.F.Player–again.

-I also wanted to add brushes on my GIMP and it denied it. It says that "root" is the owner..I really want to add things to my GIMP. I already downloaded brushes n stuff from deviantart and when I do try pasting it wont. What can I do in order for me to add brushes? How can I get rid of the "root"–well not rid of it–I want "root" to approve it.

May someone PLEASE explain to me step by step on what to do. I would REALLY appreciate it. Thank you!! Take care!! =)

I’m looking for a free, open source application for Linux which will allow me to make and tweak logos for web and print. Any ideas? I know that Gimp is good for editing raster stuff but I was thinking along the lines of starting on the vector side. Any help would be much appreciated!
