Tips for a reloading noob?

I know nothing about reloading ammo other than it is way cheaper. I have a friend of mine that has a reloading kit and tons of powder and if I get the other essentials he would do it for me. I saved up all my br and I bought the Lee's .45 Auto carbide die set. I am having trouble finding bullets/projectiles for it. All the ones I find are not specific and just say .45 caliber. I shoot .45 ACP or .45 Auto. Does that matter or does it work for all .45? Also, is that everything I would need? Any tips would be appreciated.
