Good questions:

Re read the issues I posted above for the reasons for Iraq action.
Notwithstanding, geopolitically, Iraq is important. You cannot have all your eggs in one basket. With the Saudis folding to radically militant elements, they cannot be counted on. And it goes without saying what is going on in Afghanistan.
No longer is the goal of this war "regime change" or disarmament. For the first time, the president said that we're going to close the Islamic "freedom gap." This belief and faith in humanity comes from Mr. Bush's faith in God - at a time when the EU's biggest battle over a new constitution is whether or not to mention the Almighty. You can't keep freedom bottled up, or drip it out as the USSR tried to do. Remember, Reagan brought them down with his vision in the face of those who said freedom wasn't for Russians.
Today, Bush knows the Saudi royal family-types are falling apart, which is why the House of Saud wants us out so they can make the changes without appearing reactionary. But if you're going to transform that region because democracies don't use WMDs and terrorist tactics, why have we been messing with the United Nations? Why have we even reduced the standard for victory in a UN vote?
Again: we don't go anywhere to conquer or for oil. We are not rebuilding a nation here because we want to occupy it forever, or because we want oil. This war has always been about giving freedom to 23 million Iraqis and protecting our own security - nothing but. Now, it's official.
