possible FAA action... flight or fight?

I got in a little trouble with the FAA and they want to take my license
for 6 months. Now their case isn't too strong (and based very much on
the subjectivity of "safe" and not on any clear cut violation of a
FAR). I'm trying to decide whether to fight it (expensive attorney
fees) or just suck it up and take some time off flying (which I
desperately don't want to do since I fly a lot and use my plane for
business).

1. Will this follow me the rest of my life or is it like speeding
where after so many years (3, etc) it's off your record?

2. What are the implications of having a violation on my record if I
decide to get a flying job in the future? How seriously do employers
look at violations? Is it a thing where I won't even get called in
for an interview if I have one on my application or will they normally
call me in so I can explain things in an interview?

3. Any rough idea how it affects insurance rates if there's a
violation (like XX% or something)?

4. Is it worth fighting the FAA- how often do folks actually win?
I've only heard horror stories and it seems like a GA pilot really
doesn't have much of a chance.

5. How negotiable is the FAA regarding the 6-month suspension- have
any of you been able to talk them into something else like a shorter
time (30 days or 60 days) or maybe community service?

I would appreciate any comments from folks that have been through this
before (vs just speculation).
