Yes - if you prefer Gnome. I use Kubuntu which is "Ubuntu" but KDE flavour. If you have Edgy look at the Unofficial Ubuntu 6.10 (Edgy Eft) Starter Guide at http://ubuntuguide.org/wiki/Ubuntu_Edgy. If you have Dapper look at the Unofficial Ubuntu 6.06 (Dapper Drake) Starter Guide on http://ubuntuguide.org/wiki/Dapper
The Ubuntu Forum is a red hot place where experts are waiting to jump on any questions. They move down the page extremely quickly. The Kubuntu Forum is a quieter place.
One of the best things to do, which I have been told off by the purists more than once, is to install Automatix. This is a script which will download and install lots of really useful stuff.
