I don't have the dotfile up anywhere, but I can run you through the basics really quickly:
* SPC-l gives you the layouts micro-state, which allows you to do all of this. First, set up your layout however you'd like, then open up the micro-state and run the save-as command (SPC-l-S) and that will allow you to save the layout to a layouts file somewhere deep in the bowels of Spacemacs.
* When you're ready to use your layout, use SPC-l-L to load the layout from a file. Type its name (Helm is used, so you get narrowing/fuzzy-find for free) and the layout will load. Note that if you already had another layout loaded, it will load it to the next workspace (accessible through SPC-l-<workspace-number>).

* As for the org Kanban board, check here: http://www.draketo.de/light/english/free-software/el-kanban-... To add this to spacemacs, just open your .spacemacs file (SPC-f-e-d) and add `kanban` to your `dotspacemacs-additional-packages` list.
