I'm sure there is going to be a spec on actual shaft play, but for the most part some nominal movement up down isn't going to be an issue, as the bearings fill with oil during operation.
The big thing to look for are any scrapes/damage inside the turbo housings of wehre blades may have rubbed. That's the only thing that would scare me.
With that said though, most Garrett GT turbos are still in good shape.
As far as the best/only solution to boost control is to go external gate. Check out my group buy if you're interested in having your's done.
