Answer 1

Don't add anything to these lines manually — your changes will be vanished by emacs on some events. Instead add custom variables with customize-set-variable and custom faces with set-face-attribute:

(customize-set-variable 'blink-cursor-mode nil)
(set-face-attribute 'default nil :family "DejaVu Sans Mono")

In order to customize face of some package one sometimes need to request the package first, and after that set its face:

(require 'mumamo)
(set-face-attribute 'mumamo-background-chunk-major nil :background nil)
