  We present updated calculations for observables in the processes
$^3$He($e,e^\prime p$)$^2$H, $^4$He($e,e^\prime p$)$^3$H, and
$^4$He($\vec{e},e^\prime \vec{p}\,$)$^3$H. This update entails the
implementation of improved nucleon-nucleon ($NN$) amplitudes to describe final
state interactions (FSI) within a Glauber approximation and includes full
spin-isospin dependence in the profile operator. In addition, an optical
potential, which has also been updated since previous work, is utilized to
treat FSI for the $^4$He($e,e^\prime p$)$^3$H and $^4$He($\vec{e},e^\prime
\vec{p}\,$)$^3$H reactions. The calculations are compared with experimental
data and show good agreement between theory and experiment. Comparisons are
made between the various approximations in the Glauber treatment, including
model dependence due to the $NN$ scattering amplitudes, rescattering
contributions, and spin dependence. We also analyze the validity of the Glauber
approximation at the kinematics the data is available, by comparing to the
results obtained with the optical potential.
