What a nice thread for this site.
Thomas and Steven, et al have made many good recommendations.
I would add that the best way to determine which hardcopy Bible Translation(s) for your research would be to use online versions to get a "feel".
While Biblegateway.com has been mentioned already(and I use it almost daily), biblecc.com is another great comparitive site, which allows you to compare numerous translations on a verse by verse basis. On both of these sites, you will find concordances, study guides, cross references, parallel commentaries, etc.
As far as hard copies go, I will not list all those I own here, as it is a very long list, but I would say that the NIV you purchased is wonderful (with the exception of the notes, as others have mentioned), the New Jerusalem, (ditto), the New Living (a paraphrase, with all the draw backs thereof), and the Douay-Rheims (my personal favorite for the Psalms).
Enjoy, God Bless!
