Somewhat OT, but I can also recommend Vincent Versace's "From Oz to Kansas - Almost Every Black and White Conversion Technique Known to Man", New Riders, 2013. Don't worry about the title, or the modest qualifier "Almost" - I, at least, can't detect what he's left out. It includes using LR (LR 4 when he wrote the book), as well as a Chapter on SFX Pro2, amongst a whole lot else. That said, personally, I find the latest versions of LR thoroughly satisfactory for a high percentage of my B&W conversions.
