Wheels are a VERY good upgrade, esp going from heavy stock wheels to lighter rims. Lower rotating mass makes more difference than non rotating mass.
That said, the first place to upgrade is tires and tubes. Look for lower weight and lower rolling resistance, but decent puncture resistance. Check out

Lighter weight high quality tubes will also lower rotating mass and resistance
