I just did this swap about a month ago on my Outback 3.0R. I used Whiteline outer tie rods, bushings and Cusco brace. You DO NOT need to cut your inner tie rods, they did not bottom out even with jam nuts removed.....plenty of depth in the Whitelines.
At full adjustment I was slightly toe-out. I purchased thinner jam nuts and now there is plenty of adjustment. I bought a toe measuring tool and I got to 0 degrees toe and have more adjustment to spare if needed.
VDC is giving me a little trouble. It's kicked on 3 times so far. Each time was in a medium speed right bend in 3rd gear off throttle. One time a car was following me pretty closely through the turn and that was not a situation I want repeated so I plan to disable it one way or anothe as soon as possible.
I'm re-reading this thread and checking out the linked STi threads but so far I don't see a full workaround for the VDC. Is programming an Ardurino an option? I already have one for my 6MT swap so throwing a few more codes in there might not be difficult. Or can a tuner do something to fix or disable it? I don't want any dash lights on long term.
