In my experience, which is a relative newcomer to GT fishing, you should stay away from the real high end stuff. Although, if you buy quality to start you'll get back the investment if you don't like the rod.
Being your size, you are likely not going to be an overpowering angler. I would keep the rod under 8' and don't watch any videos of Sami landing #300 fish in 5 minutes, that will not be you. A good rod would be something like a Black Hole 7'6" Nano. The nano makes the feel soft and somewhat fore giving as opposed to the graphite version. It can do stickbaits or poppers just fine and will be half the cost of others on your list. It is a PE 6 rod in my opinion which should line up well with the reel you have.
Although the Andamans serves up some big fish, it is the quantity and variety that keep you casting. Most of my fishing there was done with 100-120 gram poppers and I was as successful as the rest of the anglers.
After your first trip you will know what "type" of rod you are looking for and can move on to "higher end" more specialized products.
For the record, I have an "affiliation"(read: friends with Kilsong) with Black Hole USA but have many rods from Carpenter, Temple Reef, Black Hole, MC Works....the rod I mentioned is a good all around mid-level rod.
