Buy the manuals for the bullets and powders you are loading with. If you are using sierra bullets and Hodgen powder get those two manuals first. From there many stores have the books open so you can browse through them. Read every one of them and then write down the information. Sportsmans Warehouse has a different book for each caliber, i bought every one for each caliber.
Walmart has the best price for the RockChucker Supreme press which was 275 i believe. Its well worth it, as it has everything you need, that is not caliber specific.
As for a digital scale unless you are willing to throw 200 or more on it get a balance (i think it comes with the kit). A balance scale is much more accurate and much cheaper when you consider the parts to go wrong. Electronic scales use stress sensors and they can eaily become damaged, and also ALWAYS have error. I bought one for $40 from Sportsmans Warehouse, and it reads about .7 gn off of my 10-5-10 scale (something like that from RCBS). So if i am weighing a 40 gn charge it could be anywhere form 39.3 to 40.7 gn. With a balance scale i am able to see individual grains of H4831.
Another note about scales, i doubt that any of the scales are perfect. If you have the ability take every one out that they have in stock and weigh the same thing with all of them. Some of them will read alike, those are the ones i would pick.
Also if your anal about weight (like me) invest in a set of lab quality weights. I have .1 gn, .5 gn, 1 gn, 5 gn, 10 gn, 25 gn, 50 gn, 100 gn, 500 gn. I calibated my scale for 56.0 gn (my pet load for 270).
Work up loads slowly. When you start out ignore all of the "special" case prep. This includes Primer Pocket Cleaning/Uniforming, Flash hole deburring, neck turning. The only case prep you ABSOLUTELY need to do is case trimming. Using a good set of dial calipers. And the Supreme Kit has a lathe. All you need is a pilot. Case Length determines crimp. Unequal cases will crimp differently and that is bad jue jue. Case Deburring is a good idea as it helps prevent copper shaving, but do it lightly.
Remember that more importnat than anything (including ACUTAL powder weight) is consistancy. I have found that consistancy will get me consistant POI. I may weight something that is 45 gn and you may weigh it to be 47gn. Thats why its also important to start well below the max (the accepted norm is 7-10%).
Best advice i can give you is ask questions and read as much as you can. I learned the basics from my father, and then learned how to do precision loading. If you dont want to buy every book go to Sportsmans Warehouse and read them all. I have spent hours reading different books. An associate will come up to you, and they are usually a good person to talk to. At my store we have one guy who relaods for 68 different calibers, and another who was a Army Precision shooter. I have made friends with the guy who loads 68 calibers and now we exchange brass.
