I'm sorry, and I don't mean to step on any toes here, but I'm really going to have to disagree with putting pee pads all over the house. This is only going to confuse her, and she will learn it's okay to go pee and poop both outside and in. She needs to know what exactly is expected of her, without variation. Who owns the house? You or her? Because she will take over if you let her. She needs training, just as a child would. They don't know unless you teach them. Would you get rid of your child because you have failed to give her the appropriate training? You have to be the leader of the pack. The pack, meaning your whole family needs to take that role.
She is 10 months old now. She's not an itty bitty anymore. She shouldn't get into the habit of peeing inside. What she does need is a routine. How many times a day do you excersise her? Retrievers are very high energy, and if you don't drain that energy, you can expect bad behavioural problems. For example, chewing the couch! They need a long walk, or preferrably run, at least once a day...even following you on a bike or on rollerblades. They will not be as tempted to chew on things if their energy is drained.
If you crate train her, I wouldn't recommend letting her sleep with you in your bedroom, as that will increase her anxiety when you are gone. She needs her own place, and she needs to be lead to her spot or crate, and whether it's day or night time, she needs to be taught where she is expected to go. She should not be given treats in her crate, although she can have her bones and chew toys.
If she is chewing on something of yours, and you catch her, never take it out of her mouth. Make her surrender it. Stay calm, don't get aggrivated, and wait it out until she does. Do not praise her immediately for dropping it. Just pick it up and walk away. This will show her that you own it. If she is still looking fixated on the object, in an excited or fixated manner, once again, don't praise her. You may even have to put the object right in front of her, until she understands that she gets no praise or treats or even hears your voice except for a command. Only when she ignores the object does she get affection.
Try leaving all sorts of things around and watch her. Confront her if she heads towards any of your things. Just act like you would if you were giving a child a firm command in an assertive tone, and use your legs (just to block) and your body language to show her what is not acceptable.
Dogs don't care what you are saying to them, they only learn commands by repetition, but they will pick up on your energy. If you have nervous energy, so will they. If you are frustrated or mad, they will pick up on that. You have to stay strong and in control. It's just how they work. They are all instinctively pack members, and have a pack leader. You have to adopt the role as her pack leader.
There are many books to read that will give you lots of tips, and just my personal preference, I would suggest Cesar Millans books or videos. Please don't get rid of your dog. He is counting on you to teach him, and he only wants to learn what you want from him.
