I would agree that you may have to start potty training from scratch again. Limit food and water access (meal times ONLY, or water after exercise, ice cubes in the evening or when it is hot out) and time how long she can hold her bladder. All the basics need to be covered again.
Give her LOTS of positive reinforcement, and go easy on negative unless you catch her in the act. As Zoey's Mommy said, dogs have a very short memory span. If you come home, find the pee, and then punish, she won't understand WHY she is being punished. In the act, you do need to do something to show her it is not ok, but positive reinforcement is far more important than negative.
However, it does sound like you have bigger issues, and the peeing is just a symptom. She is up on furniture, barking excessively, etc etc. Sounds to me that she is either bored out of her brain, or has little respect for you as the alpha in the house. Dogs tend to bark either out of boredom (they are barking for attention) or if you are not home, they are barking at perceived threats, because they feel that they are not safe in the house, or that they must protect it - either way, it suggests that they are not confident that you are protecting the house when you are not there. I would go back to training 101 on ALL aspects, and start to assert your leadership.
