Achieving better than factory is more about your skill than the tools you have at your disposal. Doing the basics and matching a load to your rifle will almost surely outshoot factory ammo. You NEED a reliable scale, a good die set in your calibre and of course a press. A single stage press should be good enough to load quality ammo on. I personally use a Lee classic cast for the most part and it does a good enough job for me, but I'm not trying to win F-class matches either.
Neck trimming and neck turning are two things you eventually run into after you've loaded brass several times. The brass flows from the base to the neck, so the neck gets thicker and longer. If you have a factory rifle you probably don't need to turn the necks for a long time (if ever) as it likely has a sloppy neck diameter. Match chambers have very tight neck dimensions so a little growth creates problems. Trimming brass is also something that you may have to do sooner rather than later as you need to keep the brass below the SAAMI limits or bad things can happen with pressure.
Frist things first is get a reloading manual and read it to learn the process. From there gather tools- gun shows are good bets but so is ebay and the EE. You can get one of those starter kits as well. If your budget is your driver then you need to keep your eyes open and grab deals to grow your kit.
