ILR Person, Children Outside U.K are they eligible for Brt/C

[maidy]

My case is as follows please give your expert opinion,
I (main applicant) entered U.K on June 2008 with HSMP 2 years, (wife + child got visa as dependent same time but didn’t travel with me)
Wife+ one child entered U.K on 20th July 2009 as dependents of HSMP PBS migrant.
I as main applicant +Wife +1st child switched to T-1 General in May 2010
My 2nd child born in UK Aug-2010.
They all left U.K and went back to Pak on 30 June 2011.
Now I got my ILR last week while they are still outside U.K and their dependent visas expiring 02 June 2013. My 2nd child doesn’t have any visa in her passport because she was born in U.K and then travelled back to home country.

(Section 1(3) immediately after a parent is granted settlement/PR, their child is entitled to register for British citizenship (Section 1(3)), irrespective of child's immigration status.
Does this section applicable for children of a settled person living outside U.K

In case of wife /partner I believe she can apply as a partner of a settled person under Rules in place before 19 July 2012.
These rules require 2 year residency in U.K my partner dates are
20th July 2009 to 30 June 2011 in U.K which is 1 year and 11 months.
and her visa dates are HSMP dependent (May 2008 to May 2010) 2 years + T 1 General (dependent) 3 years (May 2010 to 02 June 2013

I need your advice what visa they will apply If they want to come to U.K in near future and which application forms are to be used, which test partner need to pass and if they apply after October 2013 what will be situation then.
