The "trick" involving air is to hold up the valves, once your remove the spring and retainers. You actually screw the fitting into the spark plug threads and it fills the combustion chamber with air. Which holds the valve up.
I suggest you read the ls1howto.com write up.

dowel rods to hold up lifters. air hose from a compression test kit to hold up the lifters. Undo the front of the pan to unbolt the pickup tube and remove the oil pump. Pick up an LSx balancer install tool from Sdparts.com to put the balancer back on unless you don't mind risking messing up the crank or bolt threads. happens some times.
Seems to take forever to do the springs one at a time. Just clear a day. I think the first time I did one was around 7 hours cuz we had to find a 3 jaw puller for the balancer. that was just cam and springs. creeping on 200k miles now and still have stock chain and pump.

Word of advice! On that pressure test fitting there is a small "cap" on it that screws into the end of the hose. On the first hole we did we didnt realize that the tip stayed in the spark plug socket, still fit in the rest of the holes and worked fine but just keep an eye out for it. We didnt realize something was messed up until I put the plug in there and it stuck out way farther than it should.

Are 4 wheel the same when dropping oil pan?

You have to take off the lower subframe link under the oil pan, but you don't have to completely remove the oil pan to do the pump. I did mine with the front axle still in the truck. Granted, it took me 2 weeks but that was because I was working in my driveway on during the evenings after work. (and I messed up the pickup tube o-ring a few times and didn't get pressure)
