Looking at your list, there are a couple of things I would change:
"-RCBS Trim Pro Case Trimmer 3-Way Cutter 22 Caliber
-RCBS Trim Pro-2 Manual Case Trimmer"
I owned the powered version of the above, including the three way cutter. I was never happy with the accuracy nor quality of cut of the trimmer. I got rid of it and now own a Dillon power trimmer. (And please note I am NOT a big Dillon fan. I bought the Dillon trimmer used.) I found I did not need the "three way" if the quality of the cut was good.
Also, when you have a lot of .223 brass, manual trimming gets TEDIOUS. So you may want to consider a power trimmer.
Final thought: If you want to stay with a manual trimmer, look strongly at the Forster, LE Wilson and CH4D trimmers. I have the Forster and it comes with most of what's needed to trim the standard calibers in the starter kit.
"-Lee Ultimate 4-Die Set 223 Remington"
If you want the best accuracy you can get, you might want to consider getting the Forster premium seating die, especially if you're reloading for High Power rifle. The Forster is a better design than the Redding and won't break if you're loading compressed loads for long range High Power competition sometime in your future.
"-RCBS Primer Pocket Swager Combo 2 "
I've had just about every variety of the on press swagers you can buy, including the RCBS one. None of them worked just right. I finally gave up and bought a used Dillon. Works great and I was able to process thousands of 223/5.56 brass without any drama. Again, I'm not a Dillon fan, just tried most everything else out there and they've got the best product in this situation.
"-Lee 4 Hole, Classic 4 Hole Turret Press Turret"
I owned one of these and it's an excellent press. If you tune it, set it up right and use all it's options correctly, you can produce 200 rounds/hour fairly easily and if you get the ergonomics right and have ever been a production operator, you can get 250-300 rounds out of it. But you'll be working hard at 300 and have to be very focused. I only sold mine because I had need to load thousands of .223 and .308, so I needed a progressive. I miss it. It's one of the truly economical and good all around presses out there. You might also want to consider buying a Lee Classic Cast single stage as a companion press. I guarantee you'll find uses for it and reloading rifle is a two stage process - 1. Brass sizing & prep, 2. priming, powder, bullet & seating.
"-Rifle charging die
-New Lee Drum powder measure"
You should be aware you can also use an RCBS or Hornady case activated powder drop and an RCBS Uniflow powder measure. Uniflows have been around a long time and are fairly easily acquired used. The case activated powder drops have been around, but people tend to not sell them much, so you'd have to get that used. The Uniflow is an excellent powder measure.
"-L.E. Wilson Case Length Headspace Gage 223 Remington"
Look also at Dillon and Ch4D for case gauges.
"and of course bullets and powder. I am looking to use Hodgdon H335"
For bullet and powder selection, think about what you are going to do with the cartridges you make. That will point you in a direction to find your components.
I hope this helps you.
