ILR on long residence and Tier 1 dependents

[zayem]

Dear All,
Could i ask you the following questions please?

i have been living in UK since Oct 2004 and currently have Tier 1 general visa valid till Apr 2016 but i am qualifying for long residence in Oct 2014 and i am planning to apply for it. My wife and 2 children( Under 7 years) were issued tier 1 general dependents (Entery clearnce) in Aug 2011 valid til May 2013 and stayed for 4 months. Then left UK and their visa expired back home. I renewed (Entery clearnce) their tier 1 visa in Jun 2013 and it is valid til Apr 2016 same is mine. Now they are living in UK since a month. I will be applying for ILR in Oct 2014 on long residence basis. Now

Q1: Are my dependents fall under new rules (July 2012) or not ? if yes, which visa do i need to apply for them? Can they live legally on the current PBS until 2016? will their time period on current PBS count towards ILR?

Q2: Can i show my self employment income (only submitted self assessment) as a sole traders from Apr 2014- Aprl 2015 to UKBA?

Q3: As a self employed person do i have to show only gross or net income of £24800.00( 3 dependents) ?

Q4: How much and for how many days do i need to have the maintenance fund for 3 dependents please?


I will be very grateful, if some one could answers me the above questions.


Kind regards
Zayem
