Probe for absences

Hi, first of all thank you all is a really useful forum.
I will apply for ILR first week of Feb 2014 using a SET(O) from a Tier 1 general.

I've completed my 5 years in the UK, I've never been more than 180 consecutive days abroad. but:

- I was 92 days abroad in the following conditions: I was in mid terms from London School of Marketing finished in Dec 2010 and my next term started Feb 2011. I finished working for a company in Nov 2010 so my wife and I went to visit our families and sort out few things in our country in that mid term. We registered before we left in the police that we intended to came back by Feb 2011. After I started to work as self employee and keep on with my studies.

What docs you suggest I should bring to justify my absence?

Does my wife have to probe her absence as well?

Thanks for your help.
