Giamom, I'm guessing it's still bladder related and she's licking because of irratation. Try putting a little cortisone cream on her vulva and seeing if htat helps the licking. I'd also take a urine sample into the vet, vulvar irritation coupled with weak bladder is fairly indicitive of bladder infection.
On housebreaking Buster, YES, you need to stand out there with him and make a huge freaky deal when he goes outside, throw a party, you couldn't be happier. If you catch him in the act (only if you catch him in the act) inside, you do another academy award performance about how mad and disapointed you are. It has to be memorable to the dog, so next time he has the urge to go, he's got black and white examples to think of--I'm the best puppy in the whole world when I go out there, I'm bad bad bad when I go inside. Use a crate or a tie down strap. You can make a tie down strap by going to the hardware store and buying 3.5' of plastic coated airline cable, put a loop on each end, a leash clip on one of those ends (I actually put leash clips on both ends) and you can fasten that around a table leg or whereever so that he can't run off to a corner and go without you seeing him, hopefully he won't want to go in the area he's tied off to. But if you let him out without going what ends up happening is he gets out there, is distracted by a butterfly or something, has some fun and then comes inside and goes--"oh yeah, I gotta pee!"
