Assuming stress-energy tensor ${\rm{T}}_{\mu}^{\nu}\equiv {\rm{diag}}~\{\varepsilon,-p,-p,-p\}$ and taking trace from both sides of Einstein field equations (EFE) one obtains the relation \begin{equation} -R=\kappa~(\varepsilon-3 p). \tag{1} \end{equation} If you know your metric you can easily calculate the energy density and pressure from (in your notation) \begin{equation}\label{pressure} \kappa~ p=-\frac{1-{A}^{-1}}{r^2}~,\tag{2} \end{equation} \begin{equation} \label{density} \kappa~\varepsilon=\frac{1-{A}^{-1}}{r^2}-\frac{1}{r}~\frac{{\rm d}{A}^{-1}}{{\rm d}r}~.\tag{3} \end{equation}
