NBA LIVE 08

Create a character who is as tall as allowed and max out his stats. Assign this character to a team and solo play against the computer. I believe that the Indiana Pacers are the team with the worst stats, so play against them. Since there are no restrictions on difficulty, play the game on "Rookie". Set the time limit to 12 minute quarters so that you can try for the other achievements at the same time.

If you have the tall CAP, then rebounding is not a problem. A rebound is done if you grab the ball after a missed shot. For a offensive rebound, you must shoot at the opponent's basket, miss, and have your player grab it on its way down. Since this is team combination for 20 rebounds, anyone grabbing it will add 1 to your total. Of course, having a tall player helps enormously.

An Easy way to get this is by creating a 7'4 player with maxed out stats. Then going to My NBA Live 08 < Settings < Game Settings < Press RB < Adjust User Sliders to Max < Press RB < Adjust Computer Settings to 0. Then go to Rules under settings and turn off 3 In the Key off, Goaltending off and Over the Back off.

Start a 12 min game on rookie and get the ball with your 7'4 character. If you don't start off with it steal the ball and go to the free throw line and press x to throw up a 15 foot layup. It will carry you to the basket. Get the rebound go back to the Free throw line and repeat 20 times. You can also keep doing this for the 56 Rebounds.
