See below.

Amplitude:

The tangent function has no definable amplitude. This is because:

as $theta->pi/2color(white)(8888)tantheta->oo$ which is undefined.

Period:

period of $tantheta=pi$

period of $tan(theta-pi/2)-2=pi$ ( No change in period )

Phases shift:

Subtracting $pi/2$ from $theta$ causes a shift in the positive/right direction by $pi/2$

Plots:
