1. Sounds like you'll be writing a "spec script."

These are about the toughest things to unload.
Check out the stats here:

2. Great. That's a feature length script.
Expect to dump a few hundred hours into writing and rewriting and re-rewriting it about a dozen times.
But be forewarned: Most directors... are directing something they wrote themselves.
Nearly
3/4 of all indie films, which this proposed dysfunctional family story certainly is, are writer/director films.
Roughly
only 1/4 of directors (that make it Sundance at least; Lord knows what the stats are on those 4,000+ films that didn't make it) are looking to direct
someone else's material.

3.
Up in the Air is a nice film.
Note that it's also a partial writer/director film.
Would you be shooting for that sort of tone, as well? A lot of seriousness with some dry humor? Old bull + new fish? Learning never ends because the world keeps changing moral of the story stuff?
4. There's a hundred different ways for writers to write.
Some start at the beginning and discover the way "there" as they write.
Some start at the end and work their way back.
I plan ahead where I want the story to go, A-B-C-D, often beginning in the middle then logically figuring out how we got here and where it logically should go, then go back and fill in the gaps with details.
You gotta figure out what works for you.
How do you plan your vacations?
Plot 'em out day+event, or just go and make it up as you go along?
Do you "know" that you want to see some things and ensure that they happen but give yourself a lotta leeway for other events?
Or do you prioritize and optimize your schedule to hit every each and every one you're interested in experiencing?
Or are you pretty content with just wandering around and whatever adventure seems to happen happens?
Approach your screenplay similarly.
http://en.wikipedia.org/wiki/Conflict_(narrative)#Three_Basic_Conflicts
Often, in these self-naveling introspective sort of films, there is an
external conflict that upon its resolution provides the answer for an
internal conflict.
The story's protagonist often has two different goals that he/she is not cognizant that they are in conflict with one another.
Typically the selfish goal is given up to claim the selfless goal at the story's end.
This creates character growth or story arc.
