If you wax there is a great product called TendSkin - you just put some on a cotton ball and wipe it over the waxed area. It keeps ingrown hairs away and slows the rate of regrowth. I highly recommend it! Don't exfoliate with a scrub or rough mit on the skin in the bikini area - it's too tender. TendSkin works a treat!
Get it waxed, and make sure you exfoliate & moisturise regularly, you can exfoliate down there but make sure you don't do it too harsh, when I had mine done I was told to buy a sponge with a rough side on it, it works a treat and only cost about 50p!!
