Let's start from the beginning here. A pilot is not, in anyway, required to stop on in position on the runway prior to takeoff. This can be requested by the pilot if he has any concerns about wake turbulence (violent wingtip vorticies) from an aircraft that had just departed. The standard wait is 2 minutes. Either that, or, ATC will instruct for you to hold for traffic seperation and/or the wake turbulence I just talked about.
Now for takeoff. During a normal takeoff, PF will announce "Takeoff" and release the brakes, and thrust levers are advanced from idle to to 50% N1 (1.1 EPR). From there, the PNF will check that both N1 fans are rotating at the same speed. Once complete the PNF will call "Stabalized" and the PF will advanced the thrust levers at around 40 knots, to the takeoff thrust setting, whatever it may be. The pilot will maintain directional control, on the runway, by using the rudders (the two pedals at the feet of the pilot and co-pilot). Upon reaching 80 knots. PNF will check the EGT guages and make sure that the takeoff N1 for each engine has been reached. If there is a 1% difference between the two engines (or three, four...) it needs to be added to the log after the flight. PNF will announce "100 Knots" at the appropriate time. When the takeoff desicion speed (V1 or Vee One), the PNF will call "V1" and soon after "Rotate". The nose is then pitched to around 12 degrees (depending on your aircraft) and ladies and gentlemen you are airborne.
After that, PNF calls positive climb and PF calls Gear Up, yadda yadda yadda you're at your destination in no time
Sorry if you were just wondering about the takeoff thrust I got a bit carried away
