>>> a few of the language books ... learn during the process of getting something done

If you learn by getting something done, I would suggest pick a small enough problem, that you can solve in that language. Just know enough upfront about any language to get started, then solve your problem in a fixed timescale of 1-2 weeks. You don't need to commit a ton of time as well, 1-2 hours daily will suffice.

You will not become an expert in that language, but will learn enough through doing which comes across in `right` interviews.

That will also keep you busy till you find the next right gig, which I am sure you will. During my last job hunt, I went through the process for 3 months. So don't lose hope, keep busy and your spirits up. Best of luck.
