Start out with a few of each style bait - jig, spinnerbait, crank, t-rig bait, topwater, jerkbait, stick bait, and ribbontail worm. From there learn when and where to throw these baits. As you progress, continue to discover new techniques and baits, but in the beginning, keep it simple.
I always like to tell beginners to study bass patterns and once you feel confident of where they are at, then experiment with how to get them to bite.
I would suggest picking up some NorthStar Custom Baits jigs and spinnerbaits to add to your collection. Start out with a few swim jigs, premier jigs, and hidden weight spinnerbaits - I always have a few tied on and even more in the boat.
As far as cranks go, I would reccomend picking up some Rapala DT's...great bait and you can find them on sale for $5.
