I have a BOM - only mine is called Voyage. It's alot of fun to do but it can be a bit hard. Your ideas are wonderful, but what you first need to decide is what size. Some of my fellow voyagers did their books 8X8 and some did the 12x12 size. The topics we did were:
yesterday, today, tomorrow (then, now, later)
it's about you then, etc.
favorite media: books, music, TV shows
A different view: how someone else thinks of you
places I've lived ( home sweet home)
101 things I love
I love.. (example life etc)
