i have kyb gr2's and they ride VERY nice. some brands to look at are kyb and tokico and of course koni. if you ever mess with your suspension you always need an alignment. so yes. a camber kit is up to you, id suggest getting one for at least the front.

 

I got skunk2 springs, struts, sway bars and front and back camber kit, my car has virtually no body roll what so ever! it handles amazingly i recommend getting everything at one time and lowering your car so much doesnt only affect the ride quality, handling drops and you risk scraping the underside of your car, i learned the hardway in my ricer days, i scraped my oilpan so much it made a hole in it and my exhaust.
