I wouldn't go with normal flourescents.
That's all you need for viewing the fish but I think you'll be happier with some healthy coraline. 1. Coralline somewhat keeps other ugly unwanted algaes from growing on your rock. 2. It's nice to look at. Plain rock really isn't that great looking, and with too low a light level they usually start growing brown algaes and stuff.
Rock with some coralline growth.

(pic is cloudy from when I got done moving the stuff over from the 75g. Ignore the little purple "rock" on the sand bed, that's a polyp colony that's not out, not a rock, lol)
Wish I had a better and recent closeup of one of my rocks, but my fish are asleep right now.
Looks better than rock covered in green or brown stuff.
If you get good live rock that already has coralline you'll definately want more than just a couple of flourescent bulbs, because if coralline starts to die it turns white. Plus, I know you're not planning on a reef tank, but you'll still get some small interesting critters on your rock with a little better lighting, and while it's nice to view fish, one of the major pluses of saltwater is the stuff you get to see on your rock.
You don't need the lights you were originally planning on though.
This would suffice.

I think you'll be happy with the Coralife skimmer. I have a 220g Super Skimmer and it's easy to use and works good.
And nothing wrong if you'd rather skimp on the lights and go for live rock. Live rock is infinately more important because it's your filtration, but if you want something that looks nice too you'll be better off with better lighting and as much live rock as possible on your budget.
