What part of VPC networking is challenging to you? I'm genuinely interested, because I find the basics of internet (IP) routing and addressing to be very straightforward. Not trivial, certainly, but it's not black magic, and I don't think VPCs require anything esoteric.
It all essentially boils down to some basic operations with binary numbers; the decimal repsresentations of IP addresses are useful shortcuts, but to really get a sense of what's happening, you need to look at the binary forms.
