Here are some interesting links to help:
analysis of prop 53
analysis of prop 54
summary of both
text of prop 53
text of prop 54
general info about this ballot
update: the link for the prop54 text was a timed session, I'll try to find a better one for y'all.
further update: replaced my original links for the texts of 53 and 54 with more easier read (and functioning) links -- thanks ktbee!
