Spouse visa extension

[shohjura]

hi guys,
my wife is around 6 months away from extending her spouse visa, I started looking into what is needed to make an extension application and here is what I am preparing for the application, please point out if I am missing anything:

-my British certificate of naturalisation
-my British passport
-our son's (born last summer in UK) birth certificate
-our son's British passport
-IELTS Life Skills B1 (which can be reused for ILR application, right?)
-my wife's passport
-my wife's travel document
-my contract of employment
-letter from my workplace confirming employment
-6 months payslips prior to application date (salary above £60k)
-corresponding 6 months bank statements
-marriage certificate with a certified translation (used in previous application)
-tenancy agreement in both of our names
-6-8 joint items for 2 years prior to application date from 2 electricity suppliers from 2 different homes, council tax bills, water bills, broadband bills.

-can I just please double check evidence of relationship-photos, messages etc like in initial application are not required?

Many thanks for your valuable advice and guidance as always
