Time to buy new shocks/struts, I have questions?

I am concidering the KYB GR-2 shocks and struts cause they are affordable and I am not a rich man but I was wondering if I should cough up the extra dough and get springs too???

If so I was thinking about the Ford motorsports B or C springs, which would be better for my stang?

Keep in mind I don't wanna lose any of my ride comfort(like it has any anyway) Cause it is still my daily driver, lowering springs would be nice but not necessary cause I worry more about ride quaility because the roads here in Indiana suck monkey balls!!!!

Will I need to buy the quad shocks also ?
Also will I need spring isolators too?

Thanks in advance on any and all info you guys give me,
Donny
