Could you do the following very simple test and post the results? This would help greatly to diagnose the problem:

- put the robot up on blocks

- command pure forward motion and observe and record what each of the four wheels is doing

- do the same for reverse, strafe right, strafe left, rotate clockwise, and rotate counter-clockwise

And one more thing: you don't need to understand all the calculations and diagrams if that is not your area of interest. There are some posts and papers which just show how to program, for example:
