This question comes up frequently and can't be simply answered. Please do a search and see how it has been answered before.
BUT, before going any further please buy something like the Lyman Reloading handbook or one of the other ones. Stay away from Sierra for now as it is not a primer on relaoding, at least that is my opinion. Lyman's book walks you trhough the entire reloading process and explains everything you need. From reading some sites, like this one, you will quickly find other neat things that make things easier. Basics is where to start and not jump too fast. Go slow and learn what you are doing and what you are getting into. Mistakes are not fun.
Once you see what you are getting into, and make a list of what you need, then you can decide how deep to go. You can spend a lot and get into it heavy, or you can spend a lot less and start slow. Your own budget will determine that. As to what to get as far as a press goes, the biggest and most important decision, you will get every different answer and recommendation immaginable. Blue, red, green, yellow, (ok maybe I went too far there), single, progessive, turret etc etc. You have to decide for yourself.
There is no one answer for a reloading outfit. Some above started a list for you. Get the book and read up on what it is all about. Go slow and you will do ok.
