Well your alignment problem of the car pulling to the right has nothing to do with your springs. And it doesn't matter what lowering springs you got, you would have the same issues. Your alignment after the install wasn't done right. And it's true that you can get away without a camber kit with the sport drop. I went for 2.5 years on the sport springs without any camber kits. And I got about 25K miles out of my zrated 18" tires which is pretty good for summer performance tires driven somewhat aggressively.
So do you "NEED" a camber kit, no. But it's true that you will get better wear and life out of your tires with a camber kit. I just recently installed a rear camber kit for my car just to extend the life of my new 18" tires.
The shop is gonna say that your camber is off and you need a kit if it's out of spec because they want to cover their butt, you can't blame them. But just because the rear is slightly out of spec doesn't mean it's not liveable.
And it sounds like you were just dropping it for the looks, which is fine. But if you really want to get the most out of your springs, match them with some performance shocks to keep them well dampened, it'll ride better.
Bottom line, if you want your car to ride as soft as stock, don't lower it. I lowered my car for looks initially, but I love the handling of performance springs and shocks, thicker sways, braces, wider grippier tires, etc.
So I can live with feeling a few bumps, in fact I like feeling more connected to the road. My wife has no complaints about ride quality in my car, and we've gone on long road trips in it, so I think it still has decent ride quality.
