You can install Ubuntu 8.04.1 by using Wubi.
You keep Windows as it is, Wubi http://wubi-installer.org/ only adds an extra option to boot into Ubuntu. Wubi does not require you to modify the partitions of your PC, or to use a different bootloader, and does not install special drivers.
Wubi keeps most of the files in one folder, and if you do not like it, you can simply uninstall it as any other application.
The above method allows you to run both in tandem so you can boot into Ubuntu most of the time and forget Vista is even installed, but at the same time always having the option of booting into Vista should you wish to to so. Wubi is totally virus and spyware free in common with everything related to Linux.
Ubuntu includes a full package of varoius entertainment software for example :
Mplayer Movie Player http://www.mplayerhq.hu/design7/info.html
Rhythmbox Music Player http://www.gnome.org/projects/rhythmbox/
GIMP Image Manipulation http://www.gimp.org/tutorials/
These and many more are included in the Ubuntu package including OpenOffice http://www.openoffice.org/
