Jim, this pretty much wraps up my wordsmithing (but not formatting) for chapter 3.  I have a couple of specific notes below, and one comment I tagged you in.
--Note on 'Understanding the Two Phases of Portlet Execution', beginning at line 471: I found this confusing, because we went into the scenario without saying 'this is what happens if we only allow a single-phased portlet execution'; instead, when I first read it I thought this was how portals did indeed work. But when you get to the end it states that this is not how portals work. I reworked most of it but it should be reviewed for detail accuracy and to ensure the original intent is intact.    
--The localization section needs reworking.
