What I use the most:
http://www.chefscatalog.com/product/92131-...c2-saucier.aspx 3 quart size. The saucier is a great pan / shape. sloped on the sides and not as deep. I use this every morning for oatmeal. And it's used a ton for regular cooking.
http://www.chefscatalog.com/product/92114-...c2-fry-pan.aspx in the 12" size. The go to standard frying pan.
http://www.chefscatalog.com/product/95125-...rench-oven.aspx in the 9 quart size. This is the go to pot for everything "big". Gumbos, pasta sauces, stews, red beans and rice, soups, pot roast etc all go here. It's expensive but worth it I think. Fantastic piece of equipment.
If it were me, I'd save up and get these 3 things. That covers a ton of what I cook.
For the All Clad, I have different stuff from their different lines. It's all good. The copper core is supposed to be the best and that's what my frying pan is. But I'm not sure it's that much better than their other lines.
Everything is hand wash. Just get used to that.
