My best advice, read everything you can!! Spend all of your spare time in the next 2-3 weeks soaking up as much information as possible. Try to get as much information as you can before you start buying equipment. Oh, and one last bit of advice, most of the people in the fish stores have no clue what they're talking about or are just out to sell you something you don't need, so take their advice with a grain of salt. There are a lot of much more knowledgable on these forums than you will find in the fish stores. That is for sure!
