How many Kanji do you think that we need to learn before we can read a japanese newspaper..

Probably depends a bit on the newspaper. The Japanese government has defined a list of about 2000 basic kanji. I believe that a reasonably educated person is expected to know about 4000. There's a list of kanji that school children are expected to know when they leave high school, but I can't place my hand on it quickly.
