I finally had some time to work on my car these past two days. My car has 138,000 miles on it. Here is what I found:
1) Compression Test:
Comp 1: 160
Comp 2: 163
Comp 3: 160
Comp 4: 162
2) Spark plugs looked okay to me. Re-gapped them to 0.028".

3) Changed the oil and opened the filter. Oil appeared normal, didn't see any glitter or sparkles in it. It was definitely over filled, so I probably didnt lose a full 2 quarts...maybe closer to 1.75 quarts.
When I opened the filter, I did find some (approx. 10) magnetic metal flakes in it. There wasn't much there, and I saw roughly similar amounts when I opened a filter 16,000 miles ago. So not sure if this can be considered normal wear and tear.
4) There were signs of a recent oil leak on thr front main seal. It did not drip, only enough to weep oil. I beleive this was likely due to high crankcase pressures.
I cleaned up the area and will check it for signs of continued leaking in 1,000 miles or so.
5) The intake tract was full of oil. It appeared to come from the valve cover breather hose connected to the intake.

I cleaned everything up (with exception to the intake manifold).
6) I'm unsure about the turbo. Impeller blades looked to be in good condition. When I gently / slowly turned the wheel by hand, it felt like it was sticking in spots, but maybe I was putting pressure on the bearings causing it to bind. However, it would spin for about a second if I gave it a twirl.
Play in the bearings seemed normal...however, I thought it felt maybe like there was a tiny bit of axial play. I'm not 100% certain though.
7) There was no oil in the exhaust...I pulled the test pipe and it looked normal.
