Help: Cutlass HSS basic setup info and tools

Hi I am new to the forum and MM, just dove in deep with 2 Cutlass HSSs, one in charcoal sparkle and rosewood, the other in faded buttercream roasted maple. I’ve got buzzing pretty much up and down the neck, the action is too low at least for my taste. No tools were included with the guitar.

(1) Can anyone tell me what size truss rod wrench is used to make neck adjustments, and (2) what size wrench is used to adjust the bridge, and (3) what size wrench is used to adjust the individual string height saddles?

Would the recommended order of adjustment be truss rod first, then bridge, then individual string height? Last, check intonation?

Excited about these guitars, but a little concerned about being able to tweek the setup to where I want it. Thanks much.
Bob
