Well for critical editions of the Bible in their ancient languages, my favorites (and a few standards used in scholarship) are:

Biblia Hebraica Stuttgartensia
Septuaginta
Novum Testamentum Graece Nestle-Aland
Novum Testamentum Graece United Bible Society (UBS)
Biblia Sacra Vulgata
Syriac New Testament and Psalms-FL UBS

For scholarly works:

“How Jesus Became God”, “Misquoting Jesus”, and “Forged” are all my favorites from Dr. Ehrman
“Ugaritic Narrative Poetry” – Simon Parker, editor
“Eerdman’s Dictionary of the Bible” which has articles from both Bart Ehrman and my mentor Anthony J. Tomasino
“Textual Criticism of the Hebrew Bible” – Emmanuel Tov
“God in Translation” – Mark S. Smith
“The Dead Sea Scrolls” – Michael Wise
“The Oxford History of the Biblical World” – Michael Coogan, editor
“Job: Introduction, Translation, Notes” – Marvin H. Pope

For Bible translations and studies:

The New Oxford Annotated Bible – Oxford
NIV Cultural Backgrounds Study Bible (my mentor did the commentary work on Esther there) – Zondervan
NASB Study Bible – Zondervan

I’ve got several bookshelves full of stuff. My current focus is the Book of Job, hence a lot of my favorites are OT and ANE related work.
