Errrrr, sorry to tell you that but social stuff and shooter games don't go along well. There are other MMO games centered around it that will satisfy those needs better.
BUT
Instead of having player housing, cities and outfit rooms, just give everyone and each outfit they'r own spaceship chambers. Basically little metalish rooms with space theme, displaying your achievements, the achievements being new possible decorations to you'r room: crush a mosquito 50 times and get a broken mosquito wing as your new achievement shelf or capture a vanu base 10 times and get a burned and torn vanu banner as your new curtain, hell it can even be like captain shepherd's chambers, if you buy anything with real cash you get your own space hamster and a Kelly Chambers on your bed.
Outfit rooms would be the same but a bit bigger, displaying the outfit's achievements.
Personal rooms are personal, while outfit are for outfit members.
AND THERE YOU GO.
