I would recommend you watch youtube videos and search this forum and read all you can. There is a ton of information out there. And its impossible to give someone a run down of the basics because its not basic. I would guess that is why most experienced guys avoid threads like this. But I will try to answer some of your questions.
Since you changed your intake, your MAF reading has been skewed. You cannot compare it to OEM for an accurate power increase. You can convert airmass into torque to measure approximate gains, but your delta is no longer accurate because of the AEM intake.
51lb hour? sure I've seen more, but changing the intake can skew the MAF readings. Changing the MAF curve can also skew these readings. I wouldn't get hung up on trying to use airmass to calculate your HP or torque.
VVT- I can be moved around but there is little to be had if anything. I used to move the cam a little in my tunes, but I don't anymore for peak HP. I do however reduce is movement down load for drive-ability.
Driver Demand Engine Torque is what the ECU thinks you're asking for from the gas pedal in regards to torque. Some cars are torque at the flywheel and some cars are torque at the rear axle after it has been multiplied by the transmission. Usually the torque at fly wheel is for manuals and the latter for autos.
No need to adjust SOI unless you change the cam.
