Where To Connect Boost Gauge: Before Or After Throttle Body?
Should it be plugged on the intake or on the tubbing before the TB?

This might sound stupid but shouldn't it go after the turbo?

Yes, you want to moniter Manifold Vacuum and Pressure, which would require you to tap into the upper or lower manifold. S4 TII's make it real easy to tee right off the signal line going from the upper intake manifold to the factory pressure sensor

Has to be after the TB, before the TB it will basically always see positive pressure.
