with regards to your radio question,i don't have any experience with either of those radio's so i can't advise you.there are some special helicopter tools you will need but not that many,a pitch guage and a blade balancer spring to mind.it can be tricky to set a helicopter up if you havent done it before,that is assuming you can at least hover,as this is required in order to set the heli up for a basic flight set up.if you have never ever flown a helicopter before,THEN IT WILL BE IMPOSSIBLE TO SET IT UP YOURSELF!this is the catch with helicopters,you must find somone who can set the heli up for you before you fly it.this can be a friend at your club or even the model shop where you bought the model.after this,you can learn to fly it on your own,unlike a model aeroplane,you don't have to have someone to take off and land for you.you progress a little at a time as fast or as slow as you like.after you have learn't to hover at will,and can take off and land perfectly,then you will be able to take off the training sticks from the bottom of your helicopter and fly without them{all begginers must have the training sticks strapped to the bottom of the heli to learn to fly}you will also then be able to set up your own helicopter!with regards to the rotor rpm,it should stay constant in flight,as the pitch increases,the throttle opens more to compensate and so the rpm stays roughly the same,this can be adjusted in the radio set up to achieve the desired response.throttle and pitch are controlled by the same stick at the same time.
