To (partially) answer my own question: I just read the in-game guild help, and that provided some answers:

a) yes, officer bonuses are active throughout the entire game, not only in guild wars

b) the help was not very clear about this, but i think the bonus is meant to apply only for the armor, not for the player's "natural" stats

c) guilds level by gaining exp. As far as i could make out, it is not required to participate in guild wars in order to level

d) the main element does provide some bonus. Additional bonuses can be purchased as this page describes.
