On the 2nd hole at US Open at Pebble Beach 2010 (6/20/10) Mickelson's drive was 395 yards.
About 400 yards+.
In the 1950's the players would average around 250 - 270 but a 300 yard drive was not uncommon.

As far as he wants
kick the ball really far
It depends how accurately and how hard you hit the ball. If you hit the ball weakly, then it won't go far; If you hit the ball strongly, then the ball is most likely to go far unless the ball goes down and hits the ground early.
Not far, I don't own one
Depends on the speed the ball travels.
