Hi and welcome!
I'll have a quick bash at answering your questions but I'm
fairly new to all this. I would suggest having a really good read through the forum, your questions are quite common and have been already covered.
Q1:what is the best book to get to give me an understanding of what we should and should not do
I'm not too sure about books, I've learnt most of what I know from this forum and other websites.
Q2:Jake is whistling alot so i guess he is happy but he is pulling feathers out and seems to shake with nerve
Was he pulling feathers before you got him? If so, he may just be bored. Try to build up a good selection of toys over time and then rotate/swap them regularly (I swap Macey's toys once a week. I also swap/rearrange her perches). You'll soon find which type of toys Jake will like. Macey loves to destroy things so I buy her 'shredding' toys and toys made from natural materials (wood/rope/cocnut shell/paper etc). I get most of my toys from here
http://www.24parrot.com/. Becareful when introducing new toys though, as some parrots get scared of new things and take time to adjust/accept them.
If Jake has only started pulling feathers since moving in with you, then this could simply be the stress of him moving. Either way, pay him alot of attention and talk to him.
Have a look through other posts regarding bathing/spraying.
Regarding the shaking. Maceys chest feathers sometimes shake/shimmer. I
think this is normal. I'm sure i read somewhere that they do this to help regulate their body temperature.
Q3:what foods are an absolute NO NO as my partner will probably feed him treats all the time
Have a look here...

Q4:We have a king Charles caviller dog,it has only been 24 hours that we have had Jake all seems ok dog is more intersted in the parrots food containers and i swear Jake is trying to copy the dogs Bark.Does anyone think having a dog in the house is going to cause psychological problems for Jake.(we will keep the dog away when Jake is out)
I don't have a dog so can't really answer. But I wouldn't think it would cause Jake any psychological problems. You're doing the right thing about keeping the dog in a different romm when Jake is out.
Hope this helps!
