Answer 1

Sublime-hooks package allows you to run packages based on event (on new, on save, etc.), so you can use it to achieve your goal. Just add this code to CSS syntax settings:

"on_pre_save_language": [
    {
        "command": "css_comb"
    }
]

If you are familiar with plugins maybe you can make a plugin that extends EventListener and override on_post_save or on_pre_save methods.
