Leaving on a Jet Plane

in as few as six weeks (possibly).  Six weeks and two days, in fact.  Should I be worried, freaked out, utterly panicked because:

• we have no pack-out date, but possibly a tentative departure date?
• we have no forwarding address..none whatsoever, er, anyone mind receiving our mail for a few weeks, anyone, anyone (say in the Annapolis area?)
• we have no idea how most of our Home Leave will be spent or where, since we have no idea when we are leaving and can’t make extremely firm commitments
• we are looking at up to 5 weeks in a hotel, totally out-of-pocket, as well as a rental car in some circumstances
• we need to leave as a family, yet one of us does not even have a passport yet?
