For naming them, you could try what the shelter I visit often does, and that's use a theme. They once had to name 70 cats that were found in a house that was left to them in a will and used a book of Disney names. I think you will feel better if you name them, but not spend much thought on each name as you would if you kept them. The ones you keep can be re-named as you come to really know them.

For 20 years, I've used 20 Mule-Team Borax to control fleas in my home and it works. It's cheap, you can get it from the supermarket on the laundry soap shelves (it's a powder fabric softener) and it doesn't smell chemical in any way. Each time I take my cats to the vet, especially during the summer, the vet combs for fleas and will barely believe me when I was that borax is the only thing I use. Do not put it on the kittens, or cats, it's only for use on objects and shouldn't be used on surfaces where the kittens will walk or roll. It's fine with cats to sprinkle it all over the carpet, but with kittens I'd just run it along the edge of the carpet by the wall and under any rugs. Also, sprinkle it under the cushions of your sofas and armchairs. As you probably know, fleas spend the majority of their time off the cat and in soft furniture where they can breed like mad. The borax dries out the flea and, more importantly the eggs and larvae. Some of my cats have always been indoor/outdoor and I've brought in some strays that were loaded with fleas. Of course, I use Revolution to hit the worst of the infestation on new cats for a few months, then rely on the borax.

Also, as another poster suggested, comb the fleas off the kitten. I've used a comb on very sick or very young kittens and then knocked the comb on the edge of a container of rubbing alcohol. Or you can comb and then crush the flea with your thumbnail against the comb. This will make you feel good and it's good for the socialization of your kittens.

By the way, congratulations on the good work you are doing. I'd love to do that too, since I'm an insomniac at times, but I work full time+ and so can't do the two-hourly feedings round the clock.
