Ok, I don't have much, in the way of configs, really, but I've added them as a git repo.
The Conky config and scripts are already in their own repo, and I've also added a repo for the GTK+/Openbox theme (this was overdue).
1.) The theming for Kupfer is already handled by the GTK+ theme, so all you'd need to do, to get that, is to set satin as your active theme. It will also theme lightdm, Chromium, and Firefox, and I plan on making Eclipse behave, in the future). The theming for Skippy-xd is in the configs, along with the configs for Compton (there is one for the user environment, as well as one for lightdm- I use both Conky and Compton on lightdm).
2.) The Conky config and scripts should require very little modification, for most people on 1080p screens. The script which generates the CPU data, for example, will adjust to the number of threads/cores on your system. If you're not on a laptop, you might want to remove the battery indicator. It also comes with the void logo and fonts. If you're not on a 1080p display, you can adjust the positions and sizes to suit your needs.
3.) The pipemenus are provided by the corgi-scripts POSIX library... there's more to it, than simply providing Ob menus... I really need to update the docs, for the new/other features. Just follow the instructions in the REAMDE- they're quite thorough, and list packages required to support the various bits of functionality.
