if you had a camber issue your alignment sucked. wheels and tires alone do NOT affect alignment. assuming you had the correct sized tires, too...
- yes, replace everything
- "camber kit" is a simple term used to fool people into buying more parts. camber bolts are like $10. or you can slot the lower mount (my preferred method). caster is not adjustable and tow is adjustable with stock parts. the coilovers themselves will not allow you to adjust camber unless the lower mounting holes are slotted. i'm assuming a "camber kit" is a set of camber bolts, which you're most likely overpaying for. 95% of parts stores offer them.
- i wouldn't even debate coilovers for a 2" drop, so just get drop springs with new struts, mounts, and bushings. you'd do coilovers if you wanted something like a 4"+ drop.
