To catch lane passes start with your 3 bar bumper against the wall. This way you wont give the defender any hints to where the ball is going. To catch the ball you should start with the 3 bar plastic player straight up and down or actually tilted toward the 5 bar. When you catch the ball you should move the plastic player on the 3 bar forward with the ball to absorb momentum. It is not that difficult to absorb momentum this way and this technique will let you catch very hard lane passes. This is sort of the same way you catch a baseball, moving the glove as you catch the ball to absorb momentum.
I watched your wall passes and looks like you are getting a good start. Remember though, basic wall passes are freakishly good passes that get through defenses even when the defense seems to cover the pass. The basic wall pass is passed along the very edge of the wall, it rides the edging. If you set the defender up against the wall, you can still almost push the ball through the opening. What most people do is add a bit of action when they hit the ball with the 5 bar. As you hit the ball at the 5 bar, make sure the ball is close to the wall. As you hit the ball pull your 5 bar toward you, giving a slight brush toward the wall. This will help ride the edge along the wall. Try to see how little room you need for a wall pass. You should be able to make the basic pass with only a tiny space between the defense and the wall.
