I can see where that would be very confusing for someone who had no previous experience. For a caretaker, I would assume the dietary laws would be the hardest to remember. Meat and dairy can't touch, for example, and there are different dishes and pots and pans for meat and dairy.
Psalms is very beautiful. I have always enjoyed the various imagery that is used. For myself, however, I tend to like the Prophets out of any other books in the Bible.
David is who i could relate to. He stumbled a lot and yet he was called the apple of G_d's eye. i find that delightful. And yes the flow of Psalms Is poetic and beautiful. One of other favorite books is Isaiah. Especially Isaiah 54:1-8
1Sing, O barren, thou that didst not bear; break forth into singing, and cry aloud, thou that didst not travail with child: for more are the children of the desolate than the children of the married wife, saith the LORD.
2Enlarge the place of thy tent, and let them stretch forth the curtains of thine habitations: spare not, lengthen thy cords, and strengthen thy stakes;
3For thou shalt break forth on the right hand and on the left; and thy seed shall inherit the Gentiles, and make the desolate cities to be inhabited.
4Fear not; for thou shalt not be ashamed: neither be thou confounded; for thou shalt not be put to shame: for thou shalt forget the shame of thy youth, and shalt not remember the reproach of thy widowhood any more.
5For thy Maker is thine husband; the LORD of hosts is his name; and thy Redeemer the Holy One of Israel; The God of the whole earth shall he be called.
6For the LORD hath called thee as a woman forsaken and grieved in spirit, and a wife of youth, when thou wast refused, saith thy God.
7For a small moment have I forsaken thee; but with great mercies will I gather thee.
8In a little wrath I hid my face from thee for a moment; but with everlasting kindness will I have mercy on thee, saith the LORD thy Redeemer.
Are the verses the same in what you read?
