Urgent help on Indefinite Leave to Remain application?!

I submitted an application for an ILR on 06/5/2014 and was asked to submit income details of my partner which we did and was received on 08/5/2014. However I have some mind bothering questions which I will need some help to either reassured myself or otherwise. My partner owned 3 bedroom house without mortgage and on around £15,000 annual salary. Because of work, I live at a different address with my two kids in a house that is rented out of £500 monthly but fully paid for by my partner until June 23rd. I am on an annual gross salary of £14758. The home office accepted that indeed I am working away from home and will end my work on June 23rd. My questions are:
1. In calculating income to the family, would the home office factor my earnings to that of my partner's income of around £30,0000 annually to be as one unit coming to our family though we live at different addresses? For clarification, all my correspondences are addressed to my partner address and none to my rented address.
2. If the home office accepts (which I do think yes) that by June 23rd, 2014 I am ending my work and moving back to my partner's home address with two kids, would my partner's £15000 or around £1250 monthly income be sufficient to cover three dependent's considering the fact that my partner's owns her house outright and no rent is paid on the property?
3. How much money is required to be submitted as income for an application of ILR for one adult and two dependents?
