Why not get it on a jig before spending any more on parts/labour? Yes it does mean more money, but at least you'll have the peace of mind.
The pre-repair pictures on the link from your other thread showed a fair bit of damage. I know that the alignment problem your having isn't where the dents were, but, it could be possible that such a bad bump has resulted in a small (barely noticable) bend in the chassis that may have been missed during the write-off inspection
