If you can live with (or even like) the commercial kitchen looks, you can't get better than Vollrath Tribute 3-Ply. They aren't cheap, but aren't All Clad prices either. They would certainly be my choice if I were buying stainless now. You've got to go through a restaurant supply or Knife Merchant. At least so far, Vollrath seems bilssfully unaware that home cooks might want to use real cookware too. Ace Mart seems to have very good prices. Watch out though, not all Tribute is 3-Ply.
Generally, it's probably most cost effective to buy your core group of cookware as a set -- which lets the Vollrath out because it's not sold that way.
That said, it also works well to buy whatever stainless you need to deal with recipes that have a lot of highly reactive ingredients like tomato and wine and mix up the rest of your pots and pans with aluminum (cheap and responsive), carbon steel (great skillets -- and you NEED a carbon omelette pan), and cast iron. You already seem to have the cast iron pretty well covered, so that's a start.
I'd add a couple of multi-ply stainless skillets or maybe one skillet and one saute (aka chicken fryer) shapes -- 10" and 12"; plus two or three stainless sauce pan shapes in the most common sizes -- including a Windsor or sauteuse shape.
From there, an inexpensive stainless "Pasta Set" with a strainer and steamer insert. Maybe a larger, inexpensive, stainless stock pot (if you need something bigger than the Pasta set comes with -- and that's it on stainless.
Then an 8" carbon skillet (for fried eggs), a 10" carbon skillet for omelettes and general saute use, and a 12" carbon skillet or saute pan/fryer because it's an incredibly useful size for cooking for more than two. If you actually do fry a lot of chicken, a 14" aluminum or preferably plain cast iron chicken fryer would do you proud.
Finally, fill out the sauce pans (if there are any gaps) with inexpensive commercial aluminum -- like Vollrath or Lincoln.
You've already got the enamel over cast braising pieces.
So there you go. Dream set.
Fugly but effective.
