worst thing a beginner does is buy a lot of colors and sizes of jigs. You don't have confidence in any of it and will waste a lot of time changing things trying to find the "magic" bait. There is no magic.
Scents sometimes help but I rarely use them and rarely get beat by someone that does. Learn to fish first then add refinments as you get better.
Get some 1/8 oz jig heads and a couple of colors of bodies. Maybe white chartreuse and black chartreuse.
The real secret to success is to learn where and how to fish. I usually start with whatever is on my line from the last trip and use it until I lose it or ware it out. I really don't care what it is. It will catch fish if you present it right in the right place. Good example is the "Sponge Bob" story.
