Scripture: Your favorite psalms?

I am trying to put together a Bible Study for Lent that focuses on the Psalms. My goal is to introduce the attendants to the Psalter in general (especially the categories of psalms, as well as where the psalms "fit" into the Bible) and then to take them through a selection of 12-24 psalms (this is only a six-week 90-minute study, so we'd do 2-4 per week). I would hope they would learn how the psalms are a model for prayer and how to pray the psalms in their own circumstances. I'd also introduce them to the Liturgy of the Hours, the Divine Office.

What I'm looking for is a selection of 12 to 24 psalms that are the richest, in references (to other parts of Scripture), Christological/Messianic character, and usefulness in personal experience. Obviously, psalms 1, 2, 22, 51, and 110 are high on my list, as are the Hallel psalms... there's so many! Perhaps I will end up extending this past Lent...

Here's my outline so far (full of information from http://www.cresourcei.org/):

• Introduction (RSV-2CE)
• The Psalter consists of 150 psalms or sacred hymns. In it we find poetical compositions of different kinds – hymns of praise, prayers for specific liturgical occasions, lamentations both of the individual and the nation, among others. There are psalms that express the deepest emotions of the human heart. They were used in, and many of them composed for, the temple worship. Some of them date back to King David, others were written shortly after the Exile. Their composition thus covers a long period. They were gradually brought together in small collections finally edited in one large collection arranged in five books. This became the hymnbook of the Second Temple.
• The Christian Church took over the Psalter and used it following the example of Jesus himself. The Psalms have always been used extensively in the liturgy and in the daily office of the priest. In the early Church lay people became familiar with them, as St. Jerome tells us.
• The numbering of the Psalms used here is that of the Hebrew Bible, which is, of course, followed in the Revised Standard Version. It varies somewhat from the Greek, which is followed y the Latin Vulgate and vernacular versions based on it. This alternative numbering is given in brackets. Psalms 9 and 10 in the Hebrew form Psalm 9 in the Vulgate. Psalms 114 and 115 in the Hebrew are counted as Psalm 113 in the Vulgate.

• What is todah? (http://www.catholiceducation.org/articles/apologetics/ap0124.html)
• An old Rabbinic teaching says: "In the coming Messianic age all sacrifices will cease, but the thank offering [todah] will never cease." A todah sacrifice would be offered by someone whose life had been delivered from great peril, such as disease or the sword. The redeemed person would show his gratitude to God by gathering his closest friends and family for a todah sacrificial meal. The lamb would be sacrificed in the Temple and the bread for the meal would be consecrated the moment the lamb was sacrificed. The bread and meat, along with wine, would constitute the elements of the sacred todah meal, which would be accompanied by prayers and songs of thanksgiving, such as Psalm 116. The word is Hebrew for "thanksgiving" although it also connotes a confession of praise in addition to gratitude. For example, Leah gave thanks to God when she bore her fourth son, and so she named him yehudah – or Judah – which is the verbal form of todah – to give thanks (cf. Gen 29:32-35).

(n. 1) Jesus is “in the law”, not “under the law”. “Day and night” can mean “without ceasing” or “in joy and tribulation”. (n. 2) The running waters are Wisdom or the Holy Spirit. The “tree” is the Lord: the “leaf” is the Word, the “fruits” are the Church established “in its season”, that is, after the Resurrection and Ascension. (n. 3)
