Buy some lead heads and assorted grub and skirt colors. Academy has a wide selection and they are rather cheap, like 1 to 2 bucks per pack. Try to buy them on clearance and you will get more for your money. Start with some natural colors like brown or gray and try brighter like chartreuse.
For bass fishing tackle, I like to use www.texasbasstackle.com and keep my business local. He's got a ton of stuff, and I can always drive out to Canyon Lake to pick something up at his physical location.
Not to mention, he has some of the best prices I've seen online anywhere!
