Logitech MX550 Revolution Keyboard and mouse combo

I've been searching forever to find a solution, a driver for the keyboard and mouse. I've found pay for solutions such as, steermouse but only for the mouse. I would really like to find some software that would enable me to use my Keyboard and mouse the their full potential. If you have this same set you probably already know my frustrations, you pay a good deal of money on your keyboard and mouse and can only use them and the base level.

If anyone has found a solution please let me know thank you.
