Rails Application Launch Checklist

As a part of my on-going effort to publish checklists on this blog, here is my Application Launch Checklist. Let me know if there's anything missing in the comments.
Configuration and Setup

• Add performance monitoring (NewRelic)
• Configure mail server (SendGrid -- get 25% off with my affilate link) or email service (MailChimp)
• Configure exception notification (Redmine as a Hoptoad Server)
• Configure Google Analytics
• Setup database backup
• Setup cron tasks
• Load testing
• Verify production configuration settings
• Verify font service has the production domain assigned

Optimizations

• Database optimization (bullet for n + 1 queries, rails_indexes, slim scrooge, query_reviewer)
• Page Responsiveness (Javascript and CSS caching with Jammit, Sprites, Asset hosts)
• Background Processing (Delayed Jobs - long running processes, email, file imports and processing, HTTP calls)

Caching

• Page Caching
• Action Caching
• Fragment Caching
• Query Caching
• Client-side Caching
• HTTP Caching

Anything missing from Firsthand Rails Template? Plugins?
NewRelic has a great series on Scaling Rails that reviews techniques for caching and database optimizations.
