You may have to turn the barrel adjuster a click or 3. Maybe none.
All are in the range of "normal". Just manufacturing tolerances.
You shouldn't need to touch the screws unless one of those adjustments are borderline.
Keep in mind, if you wanted something like a 13-26 or other combo, you CAN do that. That would probably entail a B screw adjustment, depending on how far you deviate from the 14-34.
B screw controls how close the guide pulley gets to the cogs. IF it's hitting, you screw it in. Going to something like the 13-26, you'd screw it out a bit so the pulley tracks a little closer. Chances are you'd never notice if you didn't turn it.
