blown turbo????

so im pretty sure i really blew the turbo up... just wanted to make sure.
well i ran it hard at about 15psi a couple of nights ago and heated it up pretty good and start loosing boost in third and fourth gear and then the next day made a second pull and spike way up to 20 psi and then the boost fell to 8 psi and stayed there and wouldnt boost higher. it was pour smoke out under WOT and even more under decel. then it will puff a little at idle and a fair bit on start up.there is quite a of shaft play in all directions. and i get a high pitched noise under boost as well.
the engine still runs and drives fine.

does this sound like its a blown turbo or anything else? and is there a sure way to tell with out pulling the turbo off the car?

thanks for the help in advance
