Engine dying at full throttle is definately down to High Speed Needle setting. From where you have it set, turn it an eighth of a turn clockwise. Do a high speed pass. Better or worse? If its better, your going the right way. If its worse, go an eighth the other way. Better? Go another eigth the same way. Better or worse? If its better, keep going, worse, go a 16th of a turn back etc etc.
Its hard to get right, and it is a bit of a black art initially, but take your time, make small changes and don't change more than one thing at a time.
Awkward starting is down to it being new, and not tuned quite right. If it starts, you'll get there with a bit of tuning.
Smoky grass isn't really a problem, my mate's revo does exactly the same, and smoke means that the engine isn't running too lean, which can cause damage.
Finally, revs rising may be clutch slip, but its more likely that as the engine warms up, it is running leaner, which is causing higher revs. Which is why you should tune your car for when its warm.
