I have a couple of posts in this thread that should be useful:

I just went earlier this month. A few things to add:
-there's a new Walmart and Target by the airport if you need supplies on your way into town
-Hwy 30/North loop is now mostly paved. Still a bit of a sketchy drive but the views are amazing
-ask a local about Little Beach on the weekends (it's clothing optional btw). They have people slack-lining, fire dancing and partying on Fri or Sat night
-Da Kitchen in Kihei, cheap, blue-collar, island eats
-Ululani's in N. Kihei is kinda so-so now but I still enjoy the No Ka Oi (passion fruit, mango, coconut)
-Piilani and Mokulele Hwy (31/311) speed limits are painfully slow (40/45mph). Deal with it. Almost no one goes over 55. It's an island thing.
Have fun chillin'.
