You do not need to bring your own clubs as all the courses have clubs for hire. Guestimate is about 500 baht for 18 holes.However the sets on offer are not normally new, nor the best quality, so you may want to consider bringing your own.
Shopping for copy designer clothes is best in Patong. For the real thing a trip to Robinsons in Phuket Town is best, but Patong has some smaller department stores with some decent clothes. Cheap clothes can be found at Lotus/Tescos near Phuket Town.
It's hard to say which is the 'best' seafood restaurant, but a really good one is Parlai Seafood in Chalong (seldom visited by tourists, but packed every night with Thais), but it's quite far away from Le Meridien, and Patong has its fair share of good restaurants.
Hope you have a good trip.
