For the first two, I'd go with the All-Clad Stainless line. These two pans are the workhorses of the kitchen and have to be tops. Rather than 2-10" sautes, I'd recommend a larger and a smaller one. I have 5.5 quart (12") and a 3.5 quart (10") sautes and appreciate the different sizes.
On the flip side, AC is pricy. You can get pretty comparable pans for less money. Calphalon, LeGourmet Chef and others offer the same product. I have a Claphalon SS saute pan that does a great job. I have other pieces from LeG Chef but no skillets/sautes. They all do the job as well.
Costco and BJ's have SS sets that are very good stuff and very inexpensive. You may want to consider that alternative as you can get 10-12 pieces for the cost of 1 or 2 AC. I have a Costco set of SS that is every bit as good as AC and I paid $199. for 12 pieces. I don't use the steamer insert much but the rest are regulars.
