Since she's a fast learner, she's goign to try to train you to get up and deal with her on her schedule. Don't listen to her demands. Just stay put and ignore it. Don't even say a word or flinch. She'll get the hint fast that barking gets her nothing in return.
As for the resource guarding of bones- that can get dangerous. I teach my dogs a "leave it" command. I start small with very low value treats (typically toys) and when they respond just by looking away from an object, they get a better treat than what they had. I then slowly work up to letting them have better and better things and ask them to "leave it" and I pick the items up. 90% of the time I just pick the item up and give it back to them and give a treat for letting me do that. My dogs know that by listening ot the command to "leave it" I come into their space, investigate what they have, and they get rewarded for letting me touch what they had. No fighting, battle of wills, or keep away games. The 10% of the time I dont' return their item to them they think nothing of it because they still will get a treat from me.
