Consider starting out by purchasing a combo unit (rod, reel and line). You can get these for around $100 -$150 bucks a such places as Sportsman's Warehouse in Lexington, or Bass Pro in Louisville. I'm sure Cabela's has same, provided you have a location near you.
I would suggest you consider either a "4 weight" or "5 weight" rod. You will find this sufficient for pan fish, trout and smallmouth bass.
Secondly, it will be helpful if you can locate a FF buddy near you to help you get started with some of the basic techniques. Alternatively, the are some very good instructional videos on Youtube. Also, don't forget to read the past posting in this Forum.
Enjoy and Best of Luck
PS, as far as casting, suggest you start out by learning the "roll cast". Again, Youtube.
