Hi Guapa,
Hope Phoenix is beginning to settle - it sounds like he and you are feeding off each other's anxieties... try and relax and enjoy each other, this will all seem a distant memory. I would reintroduce a clean bed - if he's disorientated the random giving and taking away of beds etc. will only confuse him more. The fact the he pee'd on his bed is an indicator that he's got so confused and anxious about where and when he can /can't go, that the he then pee'd on the place where he felt secure. Also some sensitive dogs don't like enthusiastic praise, it just confuses them, a couple of quiet softly spoken words often works best.
There is a truly excellent canine behaviourist, Dr Ian Dunbar, and on his site he is allowing anyone to download his book, 'After You Get Your Puppy' FREE as part of his shelter dog prevention month. You will find some excellent advice and protocols dealing with all puppy and dog issues including house training

Good luck and hope things start to improve.
