wine users - Apr 2009 - Wine for Xubuntu?

Which version of wine should be used for Xubuntu? I'm pretty sure it's
the one for Ubuntu (and if I'm correct, which one should I use? ex) Jaunty,
etc.), and if not, which one?

9.04=jaunty
8.10=ibex
8.04=hardy

Xubuntu = Ubuntu. And why isn't Ubuntu (Gnome) called Gubuntu.

Because Ubuntu with Gnome is the first Ubuntu used as a base for all the others?

But yeah, XUbuntu is Ubuntu, so just use the Ubuntu repository.
