Sounds fine to me.
Next time you can avoid pulling the crank case plug by doing this:
After you drain the reservoir, with the ignition off, pull your recoil rope about 10 times. You'll see more oil drain from the reservoir. Repeat this a couple of times. When doing this, your oil pump is sucking up the oil in the crank case and sending it back to the reservoir.
As far as the "priming" step in the instructions, that can usually be skipped. After your oil change is complete and you have added your 2 quarts, your dipstick should show that it's over full. Crank the engine for a few seconds, shut it off, then check the oil again. It should now show that it is at the full mark, or just a little below. If it's still over full, you can try again and if it doesn't work, then you'll have to prime it.
