Just did this today. Was my first repair on this car since I bought it two months ago. It is still under the powertrain warranty and I am actually taking it in Monday for another reason but I wanted to do this myself first because I prefer to do my own work when possible.
My old gaskets were a bit oily as well. Not quite as much as the picture above but I wouldn't worry about it. Also my car was also smoking a lot on the turbo side as well but I knew I spilled a bit of coolant out of the reservoir and expected some burning. It was more than expected though and it didn't really smell like antifreeze but it went away after a few minutes.
I do recommend taking the reservoir off. It made things a bit easier.
The drivers side was definitely hardest . I did it without help though. I used a box wrench and wedged it between the manifold and tgv where one of the bolts passes through. I figured it was safe since that is not a sealing surface. My 19mm box wrench was sufficiently thick enough to hold the gap wide enough to remove and install the gaskets.
I also removed the rubber coupler from the tb to the tmic to get more room on the back side. If you do this just remember how it is oriented because it has to go back the right way for the intercooler to mount properly. I didn't realize this and I probably spent an extra hour trying to get that right.
My car seems to idle better after the fix, but I still feel a little a bit of a stumble which I guess I will mention to the service department when I bring it in Monday. It did help though and I'm glad I did it.
