Well,
From my R/C days:
camber = whether your tires are tilted towards eachother at the top or not. Matters in cornering for contact patch concerns.
toe = like it sounds. Like feet your tires can be pointed at eachother or away from eachother. Pointed towards eachother makes for twitchiness, away, stability.
caster = the tilt of the pivot holding your suspension/steering assembly. Forward = +, rearward = -.
