You're off to a good start, I think. A couple of tips--
Consider calling Kempf's to change the order slightly:
1. Add a balance-beam scale (I like the Lee; many don't) and consider NOT getting the digital. (There's better ones for less, if you still want one).
2. Make sure you have an Adjustable Charge Bar with the Pro Auto Disk Package.
3. I'm assuming you ordered two extra turrets--e.g., one each for the 38/357 and .45ACP die sets. If not, get those--or at least tell the SO they can be a stocking stuffer.
Personally, I would also add a couple of (Wilson) MAX cart gauges, but you can get by with your chambers.
Any other questions, feel free to ask.
