We use the Jordanville translation. Whenever there is a question of translations, it seems like the old ROCOR versions are always the best. They always used good, traditional English, and there was never a question about innovation in their doctrine (as with, perhaps, the OCA, which produced its own translations of all the Church hymns).
There are several styles for singing it. I know people in the Greek tradition will sing it differently than people in the Russian tradition, as with anything. For the Russian way, there is a recording you can buy online at this website: http://www.ocrb.org/products/akathist-t ... 3-download. If you can read music, the Book of Akathists that Jordanville puts out has sheet music for two styles of singing akathists. Also, it's just a really great book.
