Make sure you have a place where you can load in peace, otherwise you will make a mistake. Start loading on the light side. handgun ammo is easier than rifle for a beginer, .40cal cases are less sticky than 9mm in the dies as 9mm is a tapered case.
I tried the Lee lube in a tube, works fine, but I find the Hornady spray lube is faster, I throw about 30 rifle shell in a tupperware, give it a good spray, put the lid on and swirl it for a minute, let dry for 20 minutes and your good to go.
Everyone has their opinions on which press to get, I find Lee's are fine for me and easy on the pocket book, the turret press will let you load pistol and rifle and swapping calibres is easy. Read up on each press, think about your budget and how much you expect to load in a year. Body parts will not fall off if you don't XY or Z press. Go to each companies website and watch the videos they post there. Each of the companies generally have really good customer service, so no worries there. If you can find someone that reloads, try out their press and watch them do it. Remember Youtube is your friend.
I wash my brass, (did it for a year before I bought my tumbler) dry it and then tumble with a little bit of car wax, get a good timer and then your tumbler can run on it's own. Get a tumbler with a sealed lid, keeps the dust down. I rarely change my media, just keep topping it up.
Take your time, read a lot, stay focused on the task while reloading. Also remember opinions are like a**holes, everyone got one. enjoy
