Hey,
The same basics apply but I've found that links to the domain and authority of the domain matter more than page authority. In terms of fast indexing, make sure you have an RSS feed. Also, if you are trying to get accepted in to Google News, do make sure you have met those requirements: http://support.google.com/news/publisher/bin/answer.py?hl=en&answer=40787. Having a news specific XML sitemap is also helpful: http://support.google.com/webmasters/bin/answer.py?hl=en&answer=74288
Why would you remove the content a day or two after publication? If you have an online newspaper, that content may still be relevant for some time after the original publication date. I've tended to keep news content around years after original publication and still gotten some traffic to those articles.
Given that, I've not has experience removing content that quickly but when I have removed content from news websites, I try to redirect the old url to the most relevant new article (if possible) or news category page (usually easier to do). This preserves link value, which is obviously important. For really old stories that don't have links or traffic, I set the article to return a 410 status on that URL to signal that page is removed permanently. Again though, I'd default to keeping the article around as long as possible.
Hope that helps.
