Marydean,
I think all of the above tips are good. Especially important are the ones about the undies, asking for pain relief (don't wait till it hurts--ask when you feel you need to rest, or about 30-45 minutes before a planned activity such as a shower) and organizing meals for the first few weeks.
I found Endone and ibuprofen to be the best pain relievers.
I think it's worth asking how the incision will be closed. My first c/sec was closed with staples and my second with a continuous suture. There was a huge difference.
You might also ask exactly where the incision will be. Mine is actually just above the pubic bone and is now completely covered by hair. This was the preferred site of my first doctor--I knew nothing about caesareans at the time. However, I'm very grateful for that. Because it's so low, it has never been irritated by clothing. Many women mention that that is a problem during the first few months especially. The cosmetic result is nicer too, although that was not important to me.
If you have a difficult recovery, you will be naturally cautious about movement, etc. However, if you have a great recovery (and I hope you do!), you still need to remind yourself to take it easy. It's a big mistake to think you can handle a normal activity level in the first month or so. Often at about 3 days after delivery you feel extra tired, and then again 10-12 days after. I think it's because those are times when you start doing a bit more. Keep in mind that if you were recovering from some other type of abdominal surgery, you would probably not try to exert yourself.
Encourage all of your nearest & dearest to think of this as an opportunity to pamper you!
