What if? You could "what if" yourself into a coma during these processes!
Cross that bridge when you come to it, if they ask him for 2008 he'll have to tell them that he does not have it, it's the truth and it is reasonable, he was here at the tail end of the year and if he did not have income then, it makes sense.
Anyway, I seriously don't think they will ask him for 2008, they are not doing an IRS audit
and USCIS really doesn't want to be overwhelmed with your paperwork, they want to see the required
evidence and some reasonable supporting evidence.
If they ask for 3 years, give what they ask for, don't second guess it!

That makes sense to me, November 2008, you were here for less than 2 months, didn't work?
But the guides do say 3 years.
Are you submitting your N400 in November 2011? Because as of then you will have been living here as a lawful resident for 3 years with your spouse who is a US Citizen, because this exception is NOT based simply on 3 years of marriage. The requirement is 5 years as a lawful resident living in the US...or 3 years living in the US as a lawful resident with you USC Spouse.
That being said...
Since there is no deadline for the N400, instead of filing in November 2011, why not just wait a couple of months, get your 2011 taxes done ASAP and submit the N400 in early 2012 with your 2009, 2010, 2011 taxes?
Then they have 3 years worth and you don't have to worry that you might come up short with the paperwork they require?

We are in Seattle and we filed for AOS in July 2008 and we were also processed through CSC we did have an interview in December 2008.
At this point your time frame seems perfectly normal and it can take longer and that is normal too.
You NOA letter gives you your legal status EAD gives your the right to work, you are fine.
At the bottom of this page there are instruction as to what happens after filing, there are important tips here, maybe this will be helpful to you?

Also, if you fill in the TIMELINE in your profile...you will be connected to other VJ members that filed around the same time as you, this will help you to see how other similar cases are progressing.
