I don't see a Vernier Caliper mentioned there. A Micrometer is also valuable. If you buy a cheap one, expect it to be frequently off by .002", so verify all readings with known quantities. I have a good one, a 6" Helios from when I was a machinist.
First, inspect your brass. Discard Berdan primed and any with splits or cracks. Done.
Sizing is straight forward. Carbide dies are terribly expensive for the .30-'06, and in the .30-'06 require lube anyway. If you are using Greek HXP surplus brass, it is really soft and it is the one .30-'06 brass I have found which needs a Small Base Sizer. I have all kinds of .30-06 brass, but not a lot of the HXP. Small Base Sizer? What's that?
If you are using Military brass, the primers will almost always be crimped in, which requires crimp removal after Sizing/Decapping. There are several types of crimp removers, some relying on cutting, some relying on swaging. I'm a swaging kind of guy, relying on the RCBS swager for 35 years. I have the Hornady cutter, and a 2-gallon bucket overflowing with milsurp brass that I just did all the primer pockets on.
There are various measuring gauges available for the .30-'06, and it is nice to have them. Case Length and Headspace are some of them. Some are combinations, others just do one. The really important ones are Case Length and Case Headspace. I like the Wilson combination Case gauge. Gauges, I no have. Looks like I need this.
With a sized, unprimed case, it is not a bad idea to take some considerable number, gently insert them in your chamber, gently close the bolt so the extractor clips over the rim, open the bolt slightly, then gently close the bolt, seeing if there is resistance to closing. Have to try this....
After Sizing/Decapping, and dealing with crimped primer pockets, measure for length. If they exceed maximum length, you need to Trim. If you don't trim, pressures will go way high. Chamfer inside and out after trimming. Have a trimmer and chamfer tool.
Priming is the same as Pistol, as is Powder charging, but having your primer at least slightly below flush is critical or you will get slamfires. Garands require a powder with a burn rate in the 3031-4895-4064 range. No belling of case mouths as with pistol. Seating bullets is the same, and while you can Crimp for the .30-'06 it should not be necessary. Need a powder funnel, and probably some scales better than my Lee's.
Trimming is the biggest pain in the neck. I used a Forster mini-lathe for many years, then got a spud that allowed it to be powered by a hand drill, then really dealt with the time demands of trimming by getting a Giraud trimmer. I have the Lyman.
