Get your hands on as many reloading manuals as possible. For standard cartridges, the Hodgdon, Speer and Lee are excellent. For some wildcats and new short magnums, the new Nosler #5 has excellent info.
Make sure that your ammo is concentric and straight. Weigh your powder charges.
For dies, I would suggest the Lee Collet die set. It comes with the FL sizer, collet neck sizer, seating die, shell holder and data for very little money. The collet sizer is probably the best neck sizer compared to any off the shelf neck die on the market (standard cartridges in SAAMI chambers).
I have used the Lee Anniversay starter kit for years. I would switch the primer pocket cleaner and neck deburrer (RCBS). Otherwise, everything is excellent. The Lee hand primer is equal or better then any on the market today. The press is accurate and durable. The total kit price would be about 1/2 the RCBS price.
Use the extra money to buy loading components. Don't worry about the tumbler yet. Fine steel wool will keep your necks clean and brass shiny. If you were handgunning, then a tumbler is a must. For rifle, the brass will wear out before it gets ugly.
if you are going to do any neck turning and/or trimming, the Forster case trimmer is excellent. I would avoid the Lyman and have no experience with the RCBS. Some prefer the hand turner that are available from Sinclair and others (K&M is a good product).
Handloading is easy, fun, and allows for tailored ammo. Start slow and keep good notes. Soon most of what is discussed will make sense and you will be able to tweak your setup to meet your particular goals.
Enjoy...
