One thing is if you know the length of the Pickets ask what the cost will be to have them all cut to length.
Sometimes it is worth the extra $.

As in stiffness along the x-x axis... depends. A small rectangular tube may have a lower stiffness than a heavy punched channel, and vice versa. Depends on the cross section. But generally speaking, the punched channel I've seen is not very stiff.
When the pickets are welded to the horizontals, it becomes a composite beam. So yes, you're right. It does contribute - but the stiffness it adds is so minuscule that you can ignore it.
I think you'll find that the punched channel is not nearly as stiff as tubing. Consider using longer pickets as supports. This is very common. If you are worried about contact rust, it's going to happen wherever you put a post in, too. If you could give me a link that has the cross section of the product you are going to be using (or even better, it's sectional properties) along with the complete dimensions of the pickets you will be using, I can estimate the expected sag for various clear spans.
If you get HSS rectangular tubing, you are probably getting ASTM A500 grade B (46,000psi). There is no advantage to using a high strength steel. The stiffness depends on the cross section and the modulus of elasticity, which is going to be 29,000ksi for any steel you get.
I'd just use .035" flux core for all of it. You'll get a more ductile weld. There will be nasty stuff on your steel that you won't have the time or patience to completely remove. If you are using a PVC curtain to block the UV from public view, that's cool. If you are putting up a curtain to block the wind, that's not necessary for flux core.
Ballpark for custom wrought iron fencing is $50-$100 per linear foot. I used the entry for 48" aluminum fence in National Construction Estimator with the LA regional prices and 25% overhead, 10% profit, and 10% contingencies to ballpark the price. There wasn't an exact entry for what you're building. Here's the results:

[QUOTE=Bodybagger;185362] This is very common. If you are worried about contact rust, it's going to happen wherever you put a post in, too.
Would powder coating and some G.E. silicone under the mounting plate bolted to the concrete help to deter contact rust? Just an idea.
Thanks,
Nick

I'd check into powder coating. Makes it look professional and it's not all that expensive considering you won't be repainting every few years. cat

I made mine using the punch channel. I made a jig out of 4x4 post, just cut a slot in the wood that the punch channel would slide into. The sled the post in the punch and weld. Start the weld on channel first it is thicker than your pickets. One thing nice about a fence like this bad weld won't matter as long as they penetrate and hold. This was my first project.

1" sg tubing for frame.

The 4x4 poles were not painted yet.
