If I had to pick three rods, they would be :
#1 6'10" medium-lite power, extra-fast action spinning rod for finesse stuff.
#2 7'3" fast action, medium-heavy power casting rod for T-rigs, jigs, etc.
#3 7' medium action, medium-heavy power casting rod for crankbaits, rattletraps, spinnerbait, etc.
Don't worry about the specifics so much, just keep it simple. And unless you're loaded I would recommend getting some slightly cheaper rods or checking out FFO.
