Depends on the rifle I'm loading for, but case prep: trimmed, deburred, chamfered, flash hole deburred. After that if it's a rifle I expect a lot out of, I don't bother weight sorting because I buy very good bullets (Berger ect) and Nosler cases (sorted to 1gr) and just keep different lots separate and shoot one lot at a time. I've found that paying the price difference for better cases means consistent neck thicknesses, and the prep is done for you. I'm an ADD kid so well yea it helps.
For my general hunting rifles that MOA is good enough I do all the case prep but I won't bother with sorting anything.
Load workup is a biggie though, I look for accuracy nodes and load in the middle of the node, this in respect to both powder charge and seating depth. So far these methods have worked well for me, I have 2 rifles that do 1/2" at 200 regularly (my shooting can be quite a different story though)
I'm pretty convinced that those 2 rifles will do better, but I hold them back.
