One thing which has not been mentioned so far is that aquariums do not fair well in bathrooms due to humidity levels. I would rather have the tank in full sunlight and decrease the amount of artificial lighting (dependent on what your current planned level of lighting is), and have a combination of the both. You may experiance some algae problems with this method, and a slight increase in temperature, but it would be better than having it in the bathroom with the humidity. Just noticed you are considering bristlenoses - these will certainly decrease the algae problems - and the fish should do fine in a slightly higher temp, so I dont see a problem there. I would buy a group of bristlenoses rather than a single one (if you can get hold of them) as they are in essence a shoaling fish. I would also avoid the killifish, as they are not a community favourite.
Oh, and silence is golden - patience is a virtue. lol.
Hope this helps, and best of luck,
