  We develop and assess the potential of several powerful techniques, designed
to investigate the details of reionization. First, we present a procedure to
probe the neutral fraction, x_HI, using the Lyman alpha transmission statistics
of high-redshift (z > 6) sources. We find that only tens of bright quasar
spectra could distinguish between x_HI ~ 1 and x_HI < 0.01. A rudimentary
application of such a technique on quasar SDSS J1030+0524 has yielded
compelling evidence of a large neutral fraction (x_HI > 0.2) at z ~ 6. We also
generate the observable, high-z supernovae (SNe) rates and quantify the
prospects of detecting the suppression of star-formation in low-mass galaxies
at reionization from such SNe rates, specifically from those obtainable from
the James Webb Space Telescope (JWST). Our analysis suggests that searches for
SNe could yield thousands of SNe per unit redshift at z ~ 6, and be a valuable
tool at studying reionization features and feedback effects out to z < 13.
