No.
Yes.
"My church is set up to enter the 'gathering area' or small hall and then enter the church itself through internal double doors. On the table just outside the doors is a family sized St. Joseph edition leatherbound (impressive - I bought one - from the church), as well as a pile of softcover NAB and Jerusalem Bibles. There might even be a D-R Challoner or two, I forget.
...The parish where I grew up (heavily Irish and Italian) probably had enough Bibles in the entranceways to supply every family that attended."
this is just an anecdote. I posted the link from the USCCB that shows Lectionaries are used, not Bibles.
Lectionaries are used by the lectors, not the congregation. Missals and entire Bibles are used by the congregation.
The Catholic Bible contains the entire OT as written in the Septuagint, which was at the time of Christ, the most widespread and utilized Scripture by the Jews - including Jesus and the Apostles."
The Septuagint was a translation of texts from the Hebrew, which can not be said to be the "most" widepread, only widespread. The Masoretic text collections were also widespread. Neither were "canonical" and each had their followers. It's not logical to conclude that the Jews removed the deuterocanonical texts, because they were never common.
Hebrew was almost a dead language at the time of Christ. Greek was the lingua franca of the world. Aramaic was the common language used by Jesus and the Apostles. Latin was the language of the military conquerors - the Romans.
Only those immediately connected with the temples knew anything of Hebrew. The common folk did not, any more than the common folk now in the West know Latin (or even French), whereas formerly they did.
There are many, many reasons to doubt that was the case. No doubt Aramaic and Greek were widespread, but there is no reason to think Hebrew was not still in use as an everyday language. Classical Hebrew was the language of the Mishnah (as well as most Dead Sea scrolls). A few hundred years later, Aramaic was used for the Gemara.
Hebrew was the language of the Jewish Scripture as it is today.
"Only those immediately connected with the temples knew anything of Hebrew."
Like the folks in the Qumran caves...

Missalettes. The only Bibles at a Catholic Mass are personal Bibles.
