Francis, does your priest chant? If he does, I think it will make so much easier to restore other parts, such as bringing chant Ordinaries, introducing Propers (even the simple English Propers). When the priest chants his parts, the congregation almost automatically chant their parts (even those who are reluctant to sing). The congregation will have enough to sing (in addition to singing their 'responses' and Ordinaries, and you probably have a couple of hymns such as communion and/or recessional), so they don't miss singing the Propers ? (I really think the congregation have more than enough to sing this way and don't really see any advantage of pressuring the congregation sing more than that. So in the true Sung Mass where the priest chant, the choir or schola has their special role in the liturgy, as well as the priest and the congregation, and the whole Mass is lifted as one beautiful canticle. To me this is the beauty of the Sung Mass of Latin rite, and it supports the holy sacrament that is distinctive from the protestant worship service. )

Francis, I will pray for you, your parish and the new pastor. The Church is giving a beautiful gift of the new translation. This advent can be a great opportunity to bring more sacred music in many OF parishes.

Most of us here already know these sites, but just in case. Here are the two most important sites for this opportunity.

Simple Propers of the Mass (Ordinary Form)
http://musicasacra.com/simple-propers-of-the-mass-ordinary-form/

A couple of weeks ago, I said here -- in response to Francis' question about the four options in the GIRM being in order of importance -- that I thought the Collection of Masses of the Blessed Virgin Mary was more explicit when it comes to the order of importance. I'm afraid this is something for the Dutch dioceses only. At the end of the Collection, in the Dutch edition there is a list of approved hymns, which is preceded by the following words:

Bij het uitkiezen van gezangen kunnen de liederen naar inhoudelijke herkomst en bron onderverdeeld worden in de volgende categorieën, welke ook de volgorde in voorrang aangeven (vgl. SC 121). Bij de eerste vier groepen kan men onderscheid maken in: a) vertaling, b) parafrase, c) allusie.
1. De voorkeur dient uit de gaan naar gezangen met de voorziene liturgische tekst uit het betreffende misformulier (met name bij de antifoon bij de intrede, de antifoon bij de communie, de antwoordpsalm en het vers voor het evangelie).
2. Waar deze ontbreken kan men andere gezangen nemen, allereerst psalmen en bijbelse cantieken, omdat deze van oudsher tot nu toe de belangrijkste plaats innemen in de liturgie.
3. Vervolgens komen gezangen in aanmerking met andere bijbelse teksten (vertaling of bewerking).
4. Vervolgens dienen de liederen te stammen uit de liturgische bronnen.
5. Tenslotte kunnen de gezangen inhoudelijk vrije tekstcomposities zijn, waarbij wel in acht genomen moet worden dat ze expliciet uiting zijn van het katholieke geloof en geschikt zijn voor de betreffende liturgische plaats en functie.
Waar toonzettingen op liturgische teksten ontbreken, verdient het aanbeveling dat deze worden gemaakt.

This is a quick translation:

When choosing songs, the songs, according to origin and source, are divided into the following categories, which also indicate the order of precedence (cf. SC 121). In the first four groups, one can distinguish between: a) translation, b) paraphrase, c) allusion.
1. Preference should be given to the singing of the assigned liturgical texts, given by the corresponding mass formulary (especially the antiphon at the entrance, the antiphon at the communion, the responsorial psalm and the verse before the Gospel).
2. When these are lacking, one can take other chants, first and foremost psalms and biblical canticles, because these traditionally have the most important place in the liturgy.
3. Then chants are considered with other biblical texts (translation or paraphrase).
4. Subsequently, the songs are from the liturgical sources.
5. Finally, the songs can be free text compositions with regard to their contents, provided they are an explicit expression of the Catholic faith and are suitable for the given location and liturgical function.
When musical compositions of liturgical texts are missing, it is recommended that they are made.
