Tier1 General - Partner Visa

Hi,

Please can I get some advise as I am due to apply for an ILR along with my husband's application(Main Applicant) in APR'2015.
I am currently in the UK on a Tier1 General (Partner) visa.

Initial Visa stamped for: 17/05/2011 - 20/05/2013 (But I stepped into the country on the 4th Sep'2011).
* My husband entered the country in July'2010 but I entered after 14 months which is 4th Sep'2011.

Visa Extension(New issue date): 24/04/2013- 24/04/2015 (Was out of the country from May'2013-Sep'2013 (5 months) due to post maternity related reasons.

my question is
1) Will a late entry be classed an absence which will further have an impact on my ILR.
2) After my extension I have left the country for 5 months.
3) Does border agency even look into my continuous period from the initial stamp of visa to extension.
4) If my husband is sure of getting his ILR does it mean I will get mine or will UKBA look at other factors like my absences and late entry.
5) I have 2 kids who were born in this country since the start I have entered England and will that have a positive response to the Visas.

I understand I am shooting a lot of questions. But these questions seems to be bothering me.
Kind assist.

Thanks
Sravanthy.
