How would you know all of those things you mentioned were right without shooting the bow, which is basically tuning it. Sometimes you can eyeball or measure things and get it close. Sometimes it's right on. Depends on how close you were picking your arrow spine and how good your form is. Often times you need to touch things up a bit by shooting the bow and adjusting things to conform to how you shoot or to respond to the set up you have.

If you are happy with the way it is shooting I would not mess with it. Paper tuning is only the begining, not the end. You set everything initially by eye or by measuremeants. Then shoot thru paper to see if anything major is wrong like spine or some sort of contact. It will also show form or grip problems. You have to be able to shoot pretty well to begin with to paper tune.

After that you group tune or tune with broad heads. Sometimes you will have to change things from where they were when you paper tuned. I normally just skip that step and go right to group tuning.

If your broad heads group well and impact where you want them to I wouldn't dink with it. It is tuned. From the looks of it your shop did a good job of setting it up and you have pretty decent form.

Quit worrying about it and have fun shooting.
