First priority is to get out of the ship and explore your new surroundings. Switch to Quinn and walk to the airlock. press buttons until vacuum suit with missing air tank turns up (obviusly, female or kzin suit wouldn't fit). Fix suit with rebreather tank from Quinn's inventory. Go out from "Lance of Truth" and just explore for a while until something interesting turns up. Don't be afraid to get lost. You won't. Just move bouth characters away from ship.
