First of all, congratulations on figuring the passage out! I'm glad that our explanations were helpful, and especially happy to see that you were able to work through the thought process for yourself and understand what you had been misunderstanding before. (This is exactly why I responded in the way I did, rather than just giving you the answer in a straightforward manner, as I believe this process of thinking through everything is important and will be more helpful to you in the end.)
Anyhow, as Toritoribe-san also says, you seem to be understanding almost everything now, as your explanations and examples are correct.
The only thing I would question/take issue with is this:

the topic particle は does not dictate the role (subject/object) of the noun it marks.
I understand は is to mark the predicate while が the subject.
Could you explain what you mean by this? Are you still referring to the example sentences, or are you saying that は is
always used to mark the predicate of a sentence?

I remembered all of a sudden that は can replace をor が for contrast or emphasis. I'm not sure if this is the case with the examples in question though.
Yes, as Toritoribe-san says, this can be more generally referred to as "topicalizing" that which is marked with は. We can't really say whether or not it's for contrast in these examples (since they're just examples with no greater context), but it
could be. "Emphasis" is a word that gets tossed around a lot that I like to avoid when possible, as it can be misleading and can obscure important distinctions/differences at times (i.e. in a certain sense of the word "emphasis", one could argue that を and が can also add a sort of "emphasis" when they are used in certain ways.)
Basically, what's happening is that the sentences are being re-ordered/re-framed so that the main topic of the utterance (the "main idea" being discusssed) is the thing that's being marked with は (that group, hair, etc.) and whatever's making it (Dick, cells located within tiny holes/pores in the skin) is being introduced as supplemental information to that. It's a rhetorical device.
