Just my opinion but I always prune a rose back pretty hard when I move it. As hard as I try I loose and damage some roots so I try to compensate by pruning the branches back. Most (but not all) roses sulk a bit when they're moved and might drop some leaves but be patient. They will recover in no time.
Hope this helps.

Most of the leaves on GT are about in the top 1/3 of the plant....so would it be ok to prune lower than the leaves? of just above some of them? I know these sound like silly questions...but I don't want to kill it.

You can prune lower than the leaves and it will put out new leaves. I've done the same as Hamp, for the reasons he stated and because the rose was just too big to handle. Keep it well watered after moving it and it will be fine. I used to cut GT back to about 4 feet after he bloomed but he will put out new growth that is back up to about 8 feet in no time. He rebloomed well with his haircut after every flush.
