There is already some great advice in this thread. Basic commands, establishing a good pack hierarchy, and rewarding her for playing in good areas and reacting properly are the most important things.
If some of these bad behaviors are already consistent you can try working with her on a leash near the problem area. You are the alpha. You are allowed to stick your limbs and shoes and whatnot anywhere you want.
For example, whilst she's on the leash (perhaps in a sit/stay or down/stay) play in *your* under the bed territory. Stick your feet under there. Reach in and put a toy there and then retrieve it.
When she gets up to investigate or if she gets upset, correct her (with whatever command or sound or signal you use to stop her...this must be consistent and clear!) and then put her back in the sit/stay or down/stay. This is your space and not her space. The leash is there so she can't make it under the bed where she has the advantage and you can't correct her. When she can watch you 'play' under the bed without reacting reward her for her good sit/down/stay and move elsewhere to play together (where you want/allow her to play).
As follow-up/maintenance you will need to continue correcting her when she approaches the underbed since she is no longer welcome to camp down there. Eventually she won't be interested in going there because you will have curbed her before it gets to the point where she gets what she wants from it...and she will learn where she *is* allowed to play and have toys.
If you haven't done so already, make sure to crate train her. Ki's behavior improved dramatically when the crate was established as his safe place. It gave him a nice cave-like den area where he could go to relax and not worry about anyone trying to take it from him or bother him. It might help your pup to have an appropriate den instead of trying to claim an inappropriate one with inappropriate behavior....and you can establish the rules that go with the crate so it isn't associated with being hyper or defensive.
I have been working with Sake and she has gotten much better. When I go to move the rug (which I do often when cleaning) and she starts to go into her "attack" mode I give her a sharp "AAHHT" and then reward her when she goes in another direction. She is totally Peanut Butter motivated so lately she has been getting a piece of dog cookie dipped in PB when she decides to take the high road and tackle her brother Miso instead of me.

You're right, I've been somewhat lax in working with my dog. He's very shy and overly reactive. Thanks for reminding me of that thread!
