I have a couple of Okuma's and I like the Integrity's. Stay away from anything that costs less than the Integrity's unless you want lightness, and just a place to put your line.
My Integrity's look like they should be light, but when I compare them to something like a Galvan Torque, they feel heavy. If you can't afford something better, then don't worry, but if you can...trust me, try fishing a river for 14 hrs straight, with a heavy 9 wt setup. You will pass out at the end of the day, and not wakeup early enough to fish the next day.
Don't get a click-drag reel. Most of them use spring steel that will rust if you use them in salt water. I have been lucky (?), so far, enough to be able to land everything I've caught in the ocean without going to the reel, so I care more about how the reel (with line) balances out the rod.
I believe Ecco has some combo setups that aren't too expensive for what you get.
Whatever you get, don't skimp on the rod...skimp on the reel...dont' skimp on the line. Buy the best that you can afford for your rod.
Everyone has their preferences. I have some friends that have tried buying cheap, but eventually get the top-of-line setups just because it's cheaper in the long run (excellent replacement policies on broken gear), so they prefer Loomis, Sage, or Winston. My budget is a little lower so I like TFO (Temple Fork Outfitters). I can get a pretty good rod for about $140.00 and they have a $25.00 no questions replacement/repair warranty.
Reddington also as a decent replacement policy. I like the St. Croix's also.
Don't get a wood insert on your reel seat. Get something that doesn't soak up water.
I have done surf fishing on a 5 wt but I wouldn't recommend it. 7 to 9 wt would probably be perfect. Some people believe in only having a floating line and the either attach splitshot, or a sinking head to get the fly down (use Looong leaders). Other people believe in a fast sink line (My new one is a type 6, my old line was an intermediate sink). Don't spend money on more than one line, unless you're going to use the rod elsewhere.
Be sure you rinse off your reel, and your rod, very well and let it dry if you can, before putting it away.
Good luck, and happy catching
