In some ways, the C.Sections I've had more times than I should have, meant bringing mum home, still pretty zonked out and latching the litter onto her which meant they were able to tuck in right away.
I tried to get each one onto a teat as they were born, whipping they away when the contractions for the next arrival kicked in again - bitches could trample or smother a puppy during the process. Have a box with a warm pad (not hot!!) in it and a soft cover for the top and put the puppies in there. Puppies can survive for some while without immediately nursing, provided they are warm because as I'm sure you know newborn puppies can't regulate their own heat. You can also keep puppies going for a little while on a glucose/water solution.
Once she's done however, I'd get her outside (if she seems to need this) to empty, on a lead, and have somebody clean up the whelping box while she's away. When she comes back in, encourage her to lay down, and restraining her if needed, gently add one and then two puppies to her teats. Don't put the whole lot on her immediately - if she's a new mum, that could freak her out. I know it's gross, but if need be, put a little of her smell (from her rear end) onto the puppies so she associates them with her.
You are going to get her checked by your vet for a shot to clean her out, and her puppies to be checked for abnormalities you may have missed, once you feel she's finished whelping?
Reading your update - we had one who would 'pee' her pups, but totally refused to have anything to do with pooh. Totally beyond her - madam! I have to do it for her, and it wasn't easy. I think a lot of the time the little ones were pretty constipated - I tried sitting them in a warm bowl of water....... gravity helped but I was more than happy once they could do this for themselves.
