None of the brands will matter if you don't get good at casting.
You might not like this idea, but you may want to consider finding a certified fly caster local to you and get some lessons first. The casting instructor will have rods for you to get the feel of if you can tell him your goals.

Looks like you're in the Houston area, you could go to Bayou City Angler or Gordy & Sons for casting suggestions before investing in a starter set up.
This.
Pretty sure Marcos Enriquez is still at Gordy and he's one of the best around. He'll take you downstairs to their casting pond and work with you. Great dude.
An 8wt for the salt (reds/drum/specks) is probably the best to start with. As you get better casting and more specialized you may want to go down to a 7 or 6wt. As one of our old OB posters who I haven't seen on here in forever, BKClark, used to say "fly fishing the bay with a 6wt is like dove hunting with a .410." And of course if you're targeting bigger saltwater stuff, especially in Florida, like tarpon or permit you'll want to go up in size. But, I've also caught 20# reds on a 6wt, 50# drum on an 8wt, and 70# tarpon on a 10wt.
In freshwater, an 8wt will be slightly overkill for bass but not crazy. However, a more all-around for Texas for trout in the Guad, bream & bass all over would be a 5wt.
As for specific brands, gear can get expensive with a quickness. If you're just starting out an Orvis Encounter outfit in the appropriate weight is a great place to start without spending a ton. Similarly are the outfits you can get from Redington.

One of these outfits will handle the vast majority of what you're liable to hook into in Texas waters whether it's freshwater or bays. That being said, before I really started spending money on high-end gear I hooked into a 25# jack crevalle that absolutely burned up a Lamson reel drag and junked the reel which is why all my primary saltwater reels are Tibor now- they're the classic Everglades, Riptide, Gulfstream reels and an original style Backcountry Wide CL- they ain't cheap but they're bulletproof and the drag on a classic Tibor might be the sexiest sound ever.
