Your compression on 2, 3 and 4 is good. 1 is a potential problem. Repeat your compression test dry then wet(squirt some oil in the spark plug hole). If the wet is a bunch better you have a ring problem. If it doesn't change much, you have a valve problem. If a valve problem, you probably need to get it fixed. Rings, not so much.
When you try running it again, swap the #1 plug with one of the others. Repeat your dead cylinder test. If the dead cylinder follows the plug, the plug is bad. By the way, if you don't have aftermarket boots on the plug end of the spark plug wires, you can do the dead cylinder test without pulling the wires. Just reach in and ground the plugs one at a time.
If the problem is rings, give the oil and gas another snakeoil treatment then learn to ignore the smoke. By the way, the oil that is burning could be coming past the stems of the intake valves. You can put valve seals on to minimize that.
