lowering with springs

ive pretty much decided on getting either H&R or Nuespeed springs, ive found them both at nearly the same price range, and they both lower the same ammount of ride height (1.75"f & 1.5"r) so you say i would need a camber? how much of one? and what would be a decent pair of shocks that would gimme a nice smooth ride? (remember im not into performance just trying to get a nice looking daily driver, no need to go all out) i just dont need something way too pricey, thats all.

if you could help me out it'd be much appreciated
