You have received a lot of useful information in this thread, but PLEASE do not consider moving forward on any of it without learning much more about reloading in general -there is so much more that you do not have a clue yet that you do not know, and much of it can be very dangerous to not know.
Buy the book Modern Reloading by Richard Lee and start reading it. Not only will it explain exactly what you do NEED and what else might be nice to have, but it will tell you exactly WHY. He only talks about Lee equipment, which is a bit of a drawback, but it is still the best place to start in my opinion. Besides, it sounds like you are considering trying out the hobby as cheaply as possible, and the Lee options are both very good and usually much lower cost than other options.
