why wait to being slashdotted to implement all these changes (limit apache memory use, CDN, caching etc)? Apache (MaxClients etc) shouldn't be configured to ever take more memory than the server's RAM and during slow hours or on a separate test server you can use 'ab' or any other tool for stress-testing. If you are 'slashdotted' basically you just want to flip a version of the site with static cached page(s). Also for web site performance YSlow and Page Speed should be mentioned; before these changes you want to make sure you are not missing on any low-hanging fruit like not compressing pages etc.
