I'll help more with this when I become a functional human being again... right now I'm just completely spent.

Thanks a bunch guys!
I read the amazon page you guys suggested, very helpful. Unfortunately Darwin was out cuddling with me in bed while Bonnie slept on top of her cage (Fast asleep for over an hour, out like a light, dead to the world). I turned my back for a single second (I really do know better at this point, parrots will be parrots) and Darwin took off to dive-bomb a sleeping Bonnie's head. Bonnie woke up horribly confused and disorientated with a green cheek conure hanging off the side of her head trying to rearrange her face. Cue screaming and squawking and pillow being thrown between them.
I snatched up Darwin, the naughty little bird and plopped her in her cage where she was scolded mildly and told she was lucky to still have two feet. Bonnie was profusely apologized to and received treats in apology for Darwin horrible and unwelcoming behavior. The two have since made up and talk to each other quietly all day. Thankfully no one was hurt. Unfortunately, Darwin lost all privilege to have naps with me while Bonnie was out, which has severely cut into her lovey-dovey time with me.
Bonnie's screaming training is actually going fairly well, she only screamed twice today and has still not bitten anyone. She comes and goes from her cage freely and is starting to feel more comfortable in her new home despite her spat with her neighborhood conure.
