You can test this, maybe with a helper.
You want about 40 mm of sag, both front and rear. Sag is how much the bike settles from wheel-in-the-air to you sitting on the bike fully geared up.
Put a cable tie around one inner fork tube. (The skinny shiny tube.) Get the front tire off the ground and slide the cable tie up against the seal. Put the front back on the ground, sit on the bike wearing your usual riding gear. Jiggle a bit to settle the suspension. Get off. Raise the front tire off the ground. Measure how much the cable tie was pushed down the tube. If it is less than 40 mm, back out the preload adjusters and test everything again. If more than 40 mm, screw down the adjusters and test everything again. If you can't get to 40 mm, tell the shop that did the work that they don't know anything, and have new spacers made so you can get to 40 mm.
For the rear, raise the rear tire off the ground, measure from the axle to a point on the rear fender. Get on, etc. Your helper measures again, subtracts from the original measure, and adjusts the shock preload adjuster to get you to about 40 mm.
All the rest of the problems you mentioned have nothing to do with new springs unless the shop guys took the bike for a ride and damaged something.
