If you have a LEE kit for your pistol, you should be able to use the press, etc. for your rifle as well. You didn't say what you got in your "kit", but some of the things you will need will be: rifle dies for your caliber rifle, a powder measure scale, a means of trimming cases (I use the LEE system, with the pilot and lock stud and cutter), a means of lubrication for the cases before you size them, a means of cleaning the cases, and components. As for powders, bullets, primers, etc,.....I don't know what you have available in S.A. Here in the states, I reload for both the .308 and the .30-06; while you will find some powders that you can use in both, you will find that those powders are usually not the best for either respective caliber. For the .30-06, I like the following: H414, IMR4350, IMR4064, and Reloader 19. In the .308, I've had good luck with H4895 and H335 (I should mention that my only .308 is a semi auto).
I stand with the others in recommending a good reloading manual.....you can find all sorts of info on the net (a lot of it just plain wrong!), and the net is a good jumping off point, but I would rely on printed manuals before I trusted any data I got off the internet.
