Can someone help me order Spooky2, like where I should start, and in what order should I read?

The first thing to do is to determine what to order and get that placed.
This page may help, although I wouldn't start with less than 2 generators, if I could afford the Essential kit: http://www.spooky2-mall.com/which-kit-to-choose

Once the order is placed, download the "Full Package: Spooky2 Starter Pack" from the Downloads page and Read enough of the User Guide to install the software.

Once the software is installed, I would watch enough of the SAMA Episode 3 to know how to select a Preset and load a generator and start it, and Load a Shell Preset, load my own programs and start that running in a Test Mode generator.

Once I was comfortable (kind of) with that, I would start studying how to connect the hardware when it arrives.

I hope this step-by-step is helpful for you to get started quickly.
Of course, if you can't find answers to problems, ask for some help.
