Whenever I am taking off in the PMDG 737 for example I only need full throttle to roll down the runway and sometime in the climb just to get the speed from 250 to 294.  I never have to use full throttle after I have my V2 speed, is this right I always thought that an aircraft goes up to the noise abatement height to bring back the throttles...If I wanted to I could go about 30 degrees nose up with full throttle and still hold my V2 speed.

Lets dig deeper here.
Say you're a subject o a noise abatement procedure.
Now you gotta remember two things here:

1) Noise is proportional to the power being developed by the engines
2) Noise is also proportional to the distance between the listener and the noise source.

So, to reduce noise, we must reduce power, and get as far away from the noise sensitive areas as quickly we can.

The first segment of a noise abatement procedure calls for a steep climb at full power, so we can gain as much height as possible we enter the noise sensitive areas.

Then we go to the 2nd segment, where the engines are throttled back to climb power while the aircraft maintains its initial nose up attitude. This flight profile continues untile either a declared height has been reached or you have passed the noise sensitive areas.

This leads into the departure profile's 3rd segment which is acceleration and cleanup, followed by the 4th phase: enroute climb.

But you should not hold the V2 speed, that's the SINGLE ENGINE safety speed, of course you will have no problems at all holding that speed and climb like a rocket with two engines operational
Aim for V2+15/20 instead, and make a selected temp. de-rate of your engines (unless the runway is wet).

I'm pretty sure you won't be able to hold some 30degrees nose-up pitch after that  :)

Yes definetly worked....could barley keep V2+20...much better
