You'll know my car when you see it (hear it!)...

I fly thru Tysons on 123 every AM around 6 and come back on some KILLER back roads to go around the beltway traffic.
So you really are right next to Tysons 1, you'll be going to that food court a lot!

I'm about 2 miles from your work. If you can get in and out of work early your commute could be pretty easy depending on where you live. One tip I'd avoid leaving work around 5-6pm. Everyone from every office building hits the road at the exact same time and the traffic is pretty bad, then throw some rain or snow in the mix and you'll have a really BAD time....

Traffic has been good lately cause a lot of folks are taking vacations or working short work weeks. It will start to get heavy again after Labor Day.
Never heard of Viking Auto, but rarely take my car to shops unless I need to... I have been to Autoscandia, they did a good job, but just a warning, they aren't cheap! As you are starting to find nothing in the DC area is, from housing to tolls to labor. Jeffs shop it near Martins Volvo in Bethesda and is a really good guy too. He really knows his performance stuff too, has a very hot s70 T5 with a RN motor w/K24 in it. Also the dealer in the area have some TB guys working there, Don Beyer and Martins. But what ever you do avoid Scandinavian Imports in Rockville, they suck! I think they have someone on SS hyping how good their shop is now. Again AVOID THEM!
About housing and commutes you should talk to Brian (Bdimag) he's living in the Fairfax near Fairlakes Mall and works near Tysons 2.
I have a GTGs at my house every so often sometimes for wrenching days. And my annual cookout/GTG in August, just have to look at my calender and figure out a good weekend to host it. But it's not a rare event to see multiple Volvos parked in front of my house. Had 7 show up for the Caravan up to Carlisle, that I do every year too. We have a good group of members in this area and meet up for lunch or dinners occasionally, last one as at Mad Fox in Falls Church, even had some of the Central Va crew drive up for that... And every Saturday morning I usually show off my Volvo at Cars and Coffee in Great Falls Va, with another guy from SS.
But if you want to meet up sometime soon let me know maybe you can swing by after work for a beer or something and I'm sure Brian and or Dave might swing by too...
