Sorry I'm a little late in joining the discussion, but it looks like you have the info you need.
The only other thing that might be a worthwhile contribution to your posting is as follows (and you might already be aware of it). There is a terrific book that was just published last year (2010) by the NorthWoods Stewardship Center in East Charleston, VT. The book is entitled "Northeast Kingdom Mountain Trail Guide" by Luke O'Brien. Within this book, there is an entire chapter devoted to Monadnock Mountain that runs from pages 116-123. These pages contain maps, trail descriptions, and a bit of history and geology thrown in as well!
