It sounds like you have your hands full. My best advice would be to worry about what YOU want. Don't worry about your brother wanting you to have one of his pups. Don't make yourself feel guilty if you can't care for a puppy right now.
Having a puppy gets better with time, but remember that along with housetraining there are other things you should be doing as well to ensure your pup grows up to have a sound temperament. Once he's finished with his shots I highly recommend a puppy class especially since he's already playing rough with your son.
I have never used Revolution, I use Frontline. I assume it works. It doesn't really REPEL bugs, but kills them upon contact. You may also want to look into natural repellants (some food additives or home made sprays) that you can use in conjunction with the Revolution.
Out of curiosity, did you brother plan this litter? If he's having trouble finding homes for his puppies, that might be a problem. Breeders tend to have significant interest in their litters before the pups even hit the ground.
