One thing at a time.
It’s been my experience that students can count syllables, and get 10 syllables into a line, far easier than they can match the iambic pentameter. The iambic pentameter only came for me after about thirty sonnets — so I think it’s less of a priority. We want students to get over three hurdles first: writing fourteen lines, writing a rhyme scheme, and writing ten syllables in a line. The iamb can come later, because it’s a “sounds like this” issue, which gets solved by kids who care about writing more than one or two.
I could have sworn that it was Dershowitz, but it’s now been at least a decade since I read the report, and the name of the lawyer has long since escaped me. It was about the time of the O.J.

As for your sonnet sequence, I like it. It conveys feelings of doubt and uncertainty, and solitude; but it’s very much rooted in internal feeling and abstract language, rather than in the macrocosmic world of objects and things and processes. I tend to lean more into the world of objects than you, but it may be an advantage in the poetry world these days.
