I am going to look at the voice leading section in this book and see how well it explains it... because the voice leading in this example would fail a test in my school. (There are doubled thirds, parallel fourths and a retrogression.)
Another thing that you should consider is getting an actual teacher or tutor... be it in person or online. I say this because the theory text book we use in my AP class will literally take 12 pages to explain something the teacher express easily in a simple explanation or even sometimes a chart. Text books contain the information but it is better to have it said to you in plain english than long-winded geeky theory talk.
Now back to the progression. there are a few ways you could look at it.
I v6MB| (F:) V/V| I6 ii6 I V43/V V I
(d:)| iv6 V i |IVMB
or if you want to go straight to F
I v6MB|
F: | ii6 V7/vi vi V/V I6 ii6 I V43/V V I
(I realize the pivots didn't come out well.)
Either would be correct. I still really don't see why one would use this to modulate, though. It works...it is just long and over complex. i don't really like it because not only does it use an incorrect resolution of a secondary, it incorrectly resolves it creating a retrogression ( I mean I know they happen and rules get broken...but in a TEXTBOOK example! really?!) I mean, you would never call something a "II" because in any key, "II" doesn't exist diatonically, making it is a secondary function. (a V/V)
Oh, and just putting it out there so there is no confusion: I am not saying modulation and voice leading are not related, I just mean the concept of modulation can be understood with out knowledge of voice leading. Using it requires voice leading knowledge. :D
