I would say the best thing to buy "First" is a reloading book or two. Definitely one from a projectile manufacture like Hornady or Sierra, and maybe a Lyman book.
Read them twice till terms like "Ogive" or "OAL" and the benefits of a "Single stage", or a "Turret" or "Progressive" Presses start to have meaning, rather than other peoples suggestions.
This will also greatly help your learning curve when you get advice from other members and their words make a lot of sense.
There are great members here to give you hands on advise and being able to relate to their advise rather than a crash course will be a big plus for your reloading experience.

BTW, I reload the same calibers as your needs on a Turret Press. If you are venturing on that direction, give me a shout, I can give you some tips.
