Let's reverse the order of the sentence:
I can recommend the book for the amazing depictions of the laws of the
universe in dialog with technology, {though} whether you will complain
about the unbearable amount of information stuffed into a single
sentence or whether you will wonder at the beauty of the elegant
expression...
As you can see, you have not formed a full sentence with though, which functions analogous to yet. We are still waiting for the other shoe to fall, for the main clause.
So you must use a word other than though. You want a connector like "regardless of" or "even if".
... regardless of whether you will complain ... or whether you will
wonder.
... even if you will complain ... or if you will wonder.
Or you can simply drop though.
I can recommend the book, whether you will complain or whether you
will wonder at...
Whether you will complain ... or whether you will wonder at ..., I can
recommend the book.
And if you want a contrast with the prior sentence:
However, I can recommend the book, whether...
That said, I can recommend the book, whether...
Nonetheless, I can recommend the book, whether ...

Sure, if you want. There's nothing pejorative or insulting about the word "Britons". However "British people" is probably more common.
Remember the issues about naming of nationalities. Not all Britons are English (many Scots and Welsh). Not everyone living in the UK is a Briton (many Irish). Moreover, many British people are immigrants or the descendants of immigrants. "Briton" is sometimes used (in context) to mean the people that were living on the island 2000 years ago, before the English arrived from the continent.
