For ember I feel like the official guides[0] are a good place to start. I found that a lot of other guides or blog posts where heavily out of date, since ember has changed quite a lot in the last couple of months. There are two other guides that I skipped over, which seemed to be pretty good [1][2].

For phonegap I always just used the official docs[3] and stackoverflow for times when i was stuck. There is one thing i can highly recommend though: Install the webview-debug plugin[4] for phonegap. With that you can make use of the awesome remote debugging functionality on android.[5]

And one more resource I can highly recommend is brunch.io[6]! It is a tool to help you structure your html/js app, it bundles all your files together, compresses them and spits out 3 files in the end: index.html, app.js and vendor.js. And that's the 3 files you put into your phonegap folder. You can even setup brunch.io to automatically push those files into your phonegap folder everytime you change something. This is not ember specific either. There are nice sceletons to get you started with backbone, spine, angular, etc..
