As for coilovers, it depends what you want and how much you want to spend... If you live somewhere with great roads and no speedbumps then go low and hard with some good quality coilovers. Not sure on skunk 2 coilovers, no 1st hand experience with them, but check out the for sale section on here as there are always high quality set ups being sold...
If the roads aren't great but you can just about live with the car being slightly lower and a bit stiffer, then progressive springs would be the best option in my opinion
