Poster is looking for Z and Phase angle, no need to go to time domain.

Or am i missing something ?

The concept of impedance is only necessary when there is an AC component: just paralleling the complex impedances won't tell you what happens in the AC case, you need the time domain to model LC tank circuits and the like.

s parameters will give you Q, BW, Z, V, I........

For sinusoidal steady state like this problem is, LaPlace offers no advantages over time-domain analysis.  All the above calculations you listed are available just as easily with time-domain.
