PC joystick+PC-->wifi<-Control servo + dc mo

hi all,iam new here,i have in my mind to make some "wood explorer RC car",i need long range control(200-300m would be great,more is better),would like control this with pc joystick connected on pc,i would like to have cammera attached to vechile,microphone,some sensors,gps would be very nice:)but for now i need just wireless control..i think use some arduino board X2,xbee X2...but dont know which board?money isnt problem,but dont want to waste money if not needed,i would like to control i think 2 servos and one,maybe 2 DC motors...is this possible?need advice which arduino boards to use?
