There is no benefit to aligning vanes with the blades. Your shop should know that. They probably do, but it sounds like they just told you that to get rid of you, a paying customer. I'd be done with that shop.
Anyway, I don't paper tune, no reason for it. It is only a beginning point and you'll need to walk-back tune and then broadhead tune anyway. Confirm that you have no fletch clearance issues. I'd start with the arrow level. Walk-back tune until your fieldpoints are falling in a vertical line. Adjust sights left-right if necessary. Then broadhead tune. Move the rest to put the broadhead in the field point group. If the broadheads hits high of the FPs, move the rest down. If the broadheads hit right of the FPs, move the rest out.
This is not hard to do, but many guys can't bring themselves to move their rest. They are convinced that they can't change anything once they get "bulletholes" in paper. The shooter is part of the overall shooting system. The geometric centershot of a given bow is usually not where it will end up for a given person, arrows, broadhead, etc.
