Check out The Church at Prayer Vol. IV: Liturgy and Time, edited by Canon A.G. Martimort.
I prefer the books, but life gets in the way. Often, when I have time to do my hours I am often no where near my books. I use iBreviary on my phone most of the time. I primarily use the books at home or at church.
As for the books, if you have a Half Price Books near you check there. I got my entire set from HPB for $32. Also, if you want to save money, don't buy the four volume set. Buy them used one book at a time as you can find deals. For example, you can snag a Volume I used on Amazon right now for $7.43 (Link).
Edit: Looks like someone already scooped up that cheap volume...
It is definitely Catholic. You can find it here: https://www.amazon.com/Christian-International-Commission-English-Liturgy/dp/1941243614
I'm not ready to shell out the money for the full set, and I also don't have time to pray the full office. Several people recommended this book, and so far it's excellent, just want to make sure I fully understand when to add the "Glory" at the end of the Psalms, etc.
IBreviary is a better solution. Works on android or iOS.

I use to pay for universalis, but it is that weird translation and it is not the same as my books,. A seminarian told me about ibreviary and I have not looked back.
Scanlon's Latin for Missal and Breviary. https://www.amazon.com/Latin-Grammar-Vocabularies-Exercises-Preparation/dp/0895550024#:~:text=Scanlon%20and%20Scanlon%20is%20a,originally%20written%20in%20the%201940's.
As with most such resources, this was created for the pre-conciliar breviary, but this book is written with learning Latin for the Office and Mass in mind.
The Benedictine Monastic Diurnal put out by Patrimonium Press uses the Douay-Rheims Challoner for its English translation, if I'm not mistaken.

The Little Office of Baltimore is also based on the Douay, I believe, and is one of the most traditional Little Offices that retains a uniquely American patrimony.

This is roughly what I'm looking for, but the amazon review mentions bad quality on the binding.
There is a long discussion of the decision-making process in a PhD dissertation by Joseph Topping (Stanislaus) Campbell, titled "Structural Reform of the Roman Office: 1964-1971" from the Department of Theology at Notre Dame, April 1987.
Unfortunately, I can't find an online copy now. The same information is also available in the book:

I'm using a combination of ribbons and book darts - ribbons for the variable parts of the offices, and book darts for anything that doesn't change.
(I'll update this comment later this evening with the sections/page numbers I have ribbons/darts in.)
A single volume "The Office of Readings" does exist, but is out of print currently.
"The Office of Readings: According to the Roman Rite" St. Paul Editions, 1983 (Boston, MA)
In the 1549 BCP, the proper psalms (where they are prescribed) are listed in the section of the book that contains the introits, collects, epistles and gospels for Holy Communion. So, for example, you'd see this for Christmas Day:
> Proper Psalmes and lessons on Christmas day. > At Mattins. > Psalms xix. xlv. lxxxv. > The First Lesson, Isa. ix. Unto the ende. > The Second Less. Matt. 1. Unto the end. > etc.
Though the 1549 table of lessons just says to use the psalms for day 25, you'd actually use Psalms 19, 45, and 85 for Christmas Mattins. I'm not sure if the Anglican Office Book includes this info anywhere, but any 1549 BCP ought to have it.
Fr. Weber's guide to psalmody, including his psalm tones (used in the Mundelein Psalter). Scribd mirror.
It's not downloadable to my knowledge, but the Mundelein Psalter has translations of many of the office hymns in English, along with the melodies. They also can be sung to simpler melodies. The hope is that the new translation of the Liturgy of the Hours will have them, but that is a ways off.
You may want to look into an updated version of the breviary.

Or if you would like to get the 4 volume set (unlike the previous link, this one has the Office of the readings): 4 volume
Absolute best (for both your questions) is a Cambridge 1662 BCP. They also have a larger size edition for about $5 more, I think it's called the "Enlarged Edition" or something like that. The 1662 is the Prayer Book nonpareil, Tom's Digest has some recent posts on why that might be.
I emailed the app developer & he told me the music came from this book. The germans did this in 1979 & as far as I can tell nothing like it exists in english.
St. Pio is more recent than the 4-vol Breviary. I found his reading and collect online. He's not in my Liturgy of the Hours Supplement either, so the only place I know to find his propers is online.
edit: The reading at my link is different from the one that was posted to /r/divineoffice from iBreviary earlier yesterday, which is also the one that Daria Sockey posted on Coffee and Canticles. I really liked reading that one; his humility in the face of his extraordinary experience is inspiring.
