The answer to all questions is I think 'no'.
You cant fly a CP with four channels. I'm not sure about the Tx but if it's the old DSM (as opposed to DSM2 or DSMX) then it wont bind to a DSMX receiver, in any case you wouldn't be able to set it up without 6 channels and appropriate heli programming features..
It cant really be set up as 'easy to fly' but with care you should be able to handle it. I leaned on a Trex 450 with no real previous heli experience. Get some training gear (the rods with foam balls on end) and take it slowly.
