Wayne L gave some good advice, but was not entirely accurate. The New World Translation (NWT) claims to "restore" the name of God to several passages in which it does *not* appear in the source texts, and these inclusions use the name "Jehovah" rather than a more scholarly transliteration of the tetragrammaton. Nevertheless, the support for these changes *are* well documented in the NWT. However, to the point of your question:
*As literature*, the bible has had more influence on Western literature than any other single work. The *most common source* *must* be the Latin Vulgate. Although there are several historic translations in most European languages, for well over 1,000 years the Latin Vulgate was the only "approved" bible, and for several centuries after the most popular "modern language" translations were translations of this Latin bible. With this in mind, the Knox bible is the most modern and scholarly English translation of the Latin Vulgate.

There appear to be no editions currently in print, but there are electronic editions, and a library copy may be available to you.
The previous English translation of the Vulgate is the Rheims-Douay Challoner Revision of 1764. This is available in print, and is historically the traditional English bible of the Roman Catholic Church.

If you plan to use a King James Version, I strongly recommend that you use only an edition which makes a scholarly attempt to duplicate the original translation. I recommend only these 3 editions:
KJV (Paragraph) - http://www.amazon.com/gp/redirect.html?ie=UTF8&location=http%3A%2F%2Fwww.amazon.com%2FKJV-Cambridge-Paragraph-Bible-Apocrypha%2Fdp%2F0521843863%3Fie%3DUTF8%26s%3Dbooks%26qid%3D1189044700%26sr%3D1-1&tag=wwwjimpettico-20&linkCode=ur2&camp=1789&creative=9325
A scholarly effort to duplicate the original KJV *translation* (as opposed to any particular printing). Spelling is modernized (not the wording) and the complete contents of the original translation is here, including the excellent marginal notes.
KJV (Oxford) - http://www.amazon.com/gp/redirect.html?ie=UTF8&location=http%3A%2F%2Fwww.amazon.com%2FBible-Authorized-James-Version-Apocrypha%2Fdp%2F0192835254%3Fie%3DUTF8%26qid%3D1190233697%26sr%3D11-1&tag=wwwjimpettico-20&linkCode=ur2&camp=1789&creative=9325
Similar to the above, this edition lacks only the marginal notes and is much cheaper (and paperback). It is pretty well-put-together for a paperback.
KJV 1611 - http://www.amazon.com/gp/redirect.html?ie=UTF8&location=http%3A%2F%2Fwww.amazon.com%2FHoly-Bible-King-James-Version%2Fdp%2F1565631609%3Fie%3DUTF8%26s%3Dbooks%26qid%3D1189044819%26sr%3D1-1&tag=wwwjimpettico-20&linkCode=ur2&camp=1789&creative=9325
This is a "replica" of the original 1611 printing. Each word on each page is in precisely the same position as in that original printing. It also includes the excellent marginal notes. The *spelling* in this edition is also identical to the original, and at 1st will cause readers some difficulty (but only at 1st). Once you have mastered the transposition of u and v, and of i and j, you will likely find it just as easy to read as an Oxford Revision KJV. Fortunately, this edition does not use the original Germanic lettering of the original, and instead uses the Roman lettering to which we are all accustomed. Possibly the best bible to use when discussing scripture with a KJV-only Christian, as this is about as close as you can get for under $100 to the *actual* *original* KJV. It is also quite reasonably priced.
If you are looking for a modern, scholarly translation, the best currently available is the New Jerusalem Bible, Regular Edition
