180 stocking questions

[boilermaker1]

This is basically what I have in mind with my upgrade.
I'm going to move everything thats in my tank now which is...
2 Cinnamon Clowns
1 Coral Beauty
1 Hippo Tang (the reason for the upgrade)
1 Starry Blenny

To this... I'd like to add:
1 Naso Tang
3-4 Anthias
1 Swallowtail Angel

Questions....
1. Naso longterm in a 180?
2. Is a 55g a big enough QT for a 3-4" Naso? I figure my 29 QT isnt gonna cut it.
3. My understanding with multiple tangs is to add simultaneously... which can be done, as I wont be tearing down my 90 until after my 180 is running... it would be a matter of transfering one out of QT and the other out of the existing DT, but is this the case? Or should I transfer 1 than the other? in what order?
4. Am I screwed adding anything else after the tangs are in the tank?
5. Anything I might be missing?

my brother has like 8 tangs in a 90, hippos are generally pretty peaceful as are nasos, but with tangs, it is best if you are going to do more than one, to do 3 or more so they don't have just one other tang to pick on if they don't like eachother, then the dominant one will keep the other from eating
