Relevance to iOS 7.1 and Xcode 5
How outdated is this CoreData course for usage in iOS 7.1 and Xcode 5? Is it worth spending time learning from here, or are there better resources available?

While it is a tad outdated (believe the projects were made in iOS 5), it's worth at least briefly going through some of the videos to give you at least an understanding of how Core Data works; what it is and what it isn't, and some of the core concepts of it. That kind of stuff is timeless.
When you're done there, you may want to check out some of objc.io's articles-- there's a whole on Core Data and another one released just recently on Syncing Data, which includes how Apple improved how iCloud and Core Data work together.
UPDATE: If you check the roadmap, while the date for it isn't announced yet, there is most definitely a Core Data project in the works.
