As a slightly less orthodox suggestion, I learned a lot of this from the 
"practice" side rather than the "theory" side, and it seems like maybe 
this is where some of your questions lie.  In addition to a textbook, you 
might find it useful to get a copy of the manual for your favorite CPU, 
which will explain, at the level of assembly language, how all these 
features work.  (They are usually available free on the manufacturer's 
website, though you may have to hunt around a bit or register for a 
developer program or something.)  You can read it in conjunction with the 
FreeBSD kernel source to see an actual example.  I found this approach 
very instructive.
