A pretty amazing new website from the Congregation for the Clergy, Biblia Clerus provides a wealth of resources.
Central to the effort is the cross-indexing of Scripture with references from the Early Church Fathers, Aquinas, important Church councils, Magisterial texts (wait…the Magisterium?? Never mind.)  and spiritual writers.
Do you know how much I could have used this in the past?

I’ve no idea how comprehensive it is – although it seems quite comprehensive. And I noted one error – the intro given to the Gospel of Matthew actually belongs with Malachi. Couldn’t find a “contact” email to notify them, though.
The English Bible translations are the RSV and the NAB.
Also at the site are the 1917 and 1983 Codes of Canon Law and the Code of Canon Law for the Eastern Churches.
