Glad you enjoy dhcpcd :)

Well, let's get it working!

That's the mistake right there.
It's not clearly spelled out in the man pages, but dhcpcd(8) says this:

 /var/run/dhcpcd.sock
     Control socket to the master daemon.

dhcpcd needs to be running in Master mode - ie on all interfaces. You're 
restricting it on the command line to wlan0.
Sadly, we need to restrict it like so to preserve legacy behavior.

Either use the -M option or allow/denyinterfaces directive in dhcpcd.conf.

I have noticed this in the dhcpcd-gtk man page, as well as others, here:

Hope this helps!
