Under the 'old-rules' ILR eligibility is 24 months living in UK as spouse.
Since your wife arrived into UK as a spouse on 29 October 2011 she may apply for ILR anytime after 1st October 2013
(28 days before the 2 year anniversary of UK entry)
In terms of those addressed documents....she'll need to provide evidence of living at the same address with you throughout the 2 year period. Just about all of those you mentioned will be OK
Take as many as you can to the checking service appointment and they will sort out the ones they need.
