Ok, one more question. Would this affect the ride quality of my car any? Cuz that would be my only reason to go back to factory height.
Spindles do not change the suspension geometry, so it should ride exactly as it would if you raised it back up.
The rear may be lowered using springs, which should ride fairly close to stock, but the bent autoride links are somewhat worrying. As far as I know, most rear lowering kits come with shortened autoride links, so maybe somebody cut the springs in the rear, hence the less-than-ideal ride?
Either way, a mild drop like the one you have will not affect the ride quality severely. I would think your issue is more likely worn out suspension components.
Last thing: That Les Schwab technician is a moron. There was no "sport" package and I don't know how you'd miss the "MCGAUGHYS" logo on the spindle if you were genuinely looking for lowering components. I would take my business elsewhere, if I were you.
