re-generate the sitemap and send it again to google webmaster tools. that will solve all crawler errors.
Update the XML sitemap again & submit it in Webmaster tool. It will take some time to get deleted old backlinks from the database & update the new ones
Good option. Also you can design and upload a custom 404 error page with links of your website. So in case a visitor reaches to an unavailable page, he/she can still continue to browse your site. Hope this helps.
its useful to fix anything broke on your site. However I have been ranking fine for years and I have many dead links/pages on my site according to GWT
