There aren't many lessons to learn from how I put my poetry collection together. Mainly I picked twice as many poems as were needed, and let the editor do the rest. I started with a poem about birth, ended with a poem about death, and tried not to jump around too much in the middle.
Below are some more comprehensive notes. They all suggest that the first and final poems matter. Some suggest breaking the book into sections. All suggest that linking devices should be used - character, theme, setting, imagery, form or even contrast. Levine suggests that if poems are "written more or less in the same creative period", they might work well in a sequence. For some poets, books have more cohesion than that. Fiona Sampson said that "Really I write books of poetry; I don't write individual poems. ... It's only really when I'm over the brow of the book that I can see what kind of collection it is that I'm writing. Then I can rewrite it all", ("The Next Review", No.5, p.13). For the final sequencing, people often suggest printing a poem per page and laying them out on the floor.
The article from the Iowa Review (you might not have access to the online version) looks at structuring ideas from many published books. The others are more practically oriented.
