No problem, have fun playing the game.
Concerning your other questions:
1. Yes, you can become head of the UN anytime. It does NOT depend on any wars you waged. But you will need a majority of votes of the other civs. And to get these votes, these civs have to like you more than any other competitor. And waging wars damages your reputation with other civs. Read the manual about reputation and diplomacy to learn how to get those votes.
2. No.
Btw, these questions do not really belong in this forum, they should be asked in the
Civ3 General or
Civ3 Strategy & Tips fora.
And we also have an EDIT button in this forum. If you forgot something in your post and want to add it, like here asking another question, it is better (also in the forum rules!) to edit your own post than to make a new one.
Thank you!
