Answer 1

Buenos Aires es la capital de Argentina
for the president, both are correct, you can use el presidente or just presidente.

Answer 2

1) OK
2) Mr. Nestor Kirchner es EL presidente de Argentina.
3) Buenos Aires es LA capital de Argentina.

Answer 3

Sentence 1 is correct
Sentence 2 would be El señor Nestor Kirchner es el presidente de Argentina
Sentence 3 would be Buenos Aires es la capital de Argentina

I can't explain why, but we Spanish talking people have this need of the article that in English is so absent. Or, as we see it, in English you have this easiness to omit the article before nouns. :)
