Welcome to the club.... Reloading rocks!
Will take a stab at a "basics" list for you.....
Resizing Lube (I use Imperial Sizing Wax)
Resizing Dies (also recommend a locking ring for each to speed setup and changeover)
A good scale (I use a dillon D-terminator)
Primer seating tool
A good set of Calipers
I'm sure I've forgotten something but am sure someone else will chime in....
