You have all the basics, just add a pork butt and you are off to the races. Will you be injecting any of the apple juice, or using it during a covered step? In addition to a coating of rub, have you considered grinding some very fine and adding it to the pulled meat, as in a 'finishing rub'. It also helps to give the pulled meat a light sprinkle of seasoned salt, or just plain salt.
The best tips for good quality pulled meat is to let the muscles tell you if they should be pulled, chunked, shredded, chopped or sometimes they need to be sliced.
You are really taking the butt apart, not really pulling it apart. It's tempting to attack it with some forks, but if you force it and get too aggressive it can look like spaghetti and can dry out faster. Here is an example of breaking down a pork butt, I do it by (a gloved) hand so I can feel the tenderness and also remove any fatty veins. You can return some of the foil juices (de-fatted) to keep it moist, or a mix of apple juice and foil juices.
This photo is on a serving line, you can visualize what I'm working with, and what I'll wind up with. I'm selecting some bark, I'll remove that fatty area below, and the muscles on the right have sort of flaked themselves.
This is a cross section of a butt, use the blade bone as reference and you will know where the most tender and flavorful muscles are. The money muscle, tubes, and horn muscles are the best. The larger loin muscles will be tighter and whiter compared to the others.
When shopping, look for a nice money muscle, this is what to look out for in the packaging. It will have the distinctive veins of fat.
