Study for and pass your private pilot written as soon as possible. Lots of computer based materials available. Buy a good headset (I liked David Clark during my ga days, Bose are awesome, but pricey. Worth the money if you will fly round motors, but that's highly unlikely)
FAA has lots of material available online for free including FAR's, Aim, flight training manuals etc.
Get a good instructor. If the one you are using is not satisfactory get another one.
