printer driver installation on ubuntu 8.10

I have an older Dell 4100 P3 384mb running Ubuntu 8.10 on a three computer network at home. One box is XP sp3, the other is a imac 2.8 Core 2 Duo. I just bought a Epson workforce 600 printer and need some help with the print drivers. Ubuntu found the printer on the network and when I was asked to pick a driver, the closest was a stylust 600 driver. When I tried it, it failed. I un-installed the printer from the available printers. I called Espon and they pointed me to sourceforce.net which has a new driver. My question is in the notes it said I must remove older CUPS with Gutenprint on a non-Macintosh system, and are upgrading from an earlier version of Gutenprint or Gimp-Print, please read this note carefully as there are special procedures that you should follow in addition to the normal procedure of running cups-genppdupdate. (http://sourceforge.net/project/shownotes.php?group_id=1537&release_id=649090). Can I remove this through the repository by removing all Gutenprint and Cups packets or must I remove them through line command? Since I a newbie on Ubuntu, I'm worried about screwing something up. Second question is there are two different packets ones a tar.bz2 and the other is ub.dmg. (http://sourceforge.net/project/showfiles.php?group_id=1537&package_id=273638) I'm assuming that I would use the latter. The next question is how do I install it? I'm been a windows boy until now and want to learn.

Any all help would be much appreciated...
