If you have XP SP2 you have IE6 at least. if you have support for tabs, then you have IE7 at least. IE8 looks a lot like IE7 and is currently at release candidate stage. You can download it from the ms website but its not finalised yet.
Do you mean Outlook or Outlook Express?
Outlook has extra crap like calander etc.... and is bundled with Office professional.
Outlook Express is most likely what you mean. It isnt maintained anymore. You are stuck with version 6.
Outlook Express doesnt exist at all on vista. On vista its called Windows Mail. This is also set to be obsoleted in the near future by the new Windows Live Mail.

Like jbennet said, the IE8 release candidate is currently available. You can also check out the IE8 blog - http://blogs.msdn.com/ie/ . It will post something as soon as they do make the announcement of the final release. So anyone interested in the final IE8 release may want to keep an eye on it.
