Welcome to Beoworld! 
1) I have seen speakers eith ad with out. It is a seperate rubber band, and have no use except for design - hence the name.
2) Dark gray mostly, but was availble in white also. The laser Beovox RL 2000 which replaced the 45.2 was available in black and white, but not gray.
3) Not from B&O - i assume.
Regards
Christian
