Welcome to the addiction. There isn't much more exhilarating than stalking a waving tail. Alternatively, it can be one of the most frustrating things to do.
I haven't fished that specific area so I can't provide locations, but chasing redfish is pretty much the same in my neck of the woods. Reds in the grass present some challenges:
The good:
Redfish are not very bright. If you can get something in front of them that vaguely resembles a food item, they will usually eat it without thought. For grass fishing I prefer a shrimp or crab pattern.
You can typically get very close to a tailing redfish. Once they have their head buried, they are pretty much a one-track mind searching for food.
Accuracy matters, but you can typically get multiple shots at a single fish.
Light tippets need not apply. In grass I'll go with 20lb to stand up from being dragged through vegetation once the fish takes off.
If you are in a good area, you will most likely have multiple fish up at the same time, choose your target wisely to not spook the rest of them.
The bad:
Fishing grass can be tough. Patterns have to have enough weight to sink in the thick grass, but light enough to not act as a depth charge when it hits the water.
Your presentation has to be right in front of the fish and at their eye level. If they are tailing their head is down and your fly has to be on the bottom, or very close to it.
Tailing red movement can be unpredictable. They can turn on a dime and head in a different direction in the search for food.
General advice:
Once you spot a fish take your time on the approach. A tailing red is a happy red and will usually continue with that behavior. Take some time to observe the behavior of the fish and direction of movement. You are better off with a well-planned presentation than a rushed one.
Also consider where the fish is going to go in the event of a hook up. Hooking it is one thing, keeping it on is another. They can slip through the grass like a snake and will get you hung up from time to time.
If the fish are cruising, I love throwing a floating crab at them, it never gets turned down and the strikes are explosive. This can be frustrating though as the underslung mouth of the redfish can make taking topwater presentations difficult. But the strike is impressive, and they will usually continue trying.
Good luck. You might want to have some blood pressure meds handy...
