Well you seem to have already gone through it pretty fast the first time. It took me ~3 weeks at 8-12 hrs/day to get the first cover-to-cover pass across, and I would never have had time for questions as well. After I finished, I started USMLE Rx.
I'm literally about 2900 questions through Rx right now, and that's obviously required, not an additional cover-to-cover pass, but instead a desultory second-pass, which has gotten me very familiar with the book. My point being: I have the feeling that a thorough and thoughtful cover-to-cover pass for me at this point would take between 1-2 weeks. For you, considering you were fast the first time and have also been doing questions, I would say a solid read in <10 days should be the goal at this point (and if you do it in a week, then even better).
