For arm-candy, I'm going with Kathla and Ranca. One to stab the Admiral's heart metaphorically, and the other to do it literally. Also, my, my, haven't we come up in the world.
For spending, I'm just going to advocate spending what we need to spend, and no more. My conception of Reinhard has always been of a man intensely uncomfortable with too much luxury and excess; the sort of Emperor who would sleep in a soldier's cot in the middle of an opulent palace. Hell, I figure that our lifestyle spending is all about creating this Gatsbyian illusion: grand rooms that are never used, grand pianos that are never played, an armory of master-crafted swords that rust in their sheaths, and all while we live in a decent, middle-class suite of rooms deep within our estate.
I know that other people may have their own interpretations, but I see Reinhard as a person very much rooted in discipline, order, and frugality. Garishly redecorating his ship isn't something he would do; he would find beauty in the silence knife-dance of ships cutting through space, in the interconnecting, shifting lanes of fire, in the interplay of stratagem and counter-stratagem. His is a glory we won't find in gold or baubles, but in the tales that will be told and retold on radio station and ansible, between the forlorn stars.
