extension date of issue : 05-04-2013 expiry till 19-04-2016.

1) I am eliglible for ILR ??(holidays might be 1 or 2 months in every yr max didnt count , as it says not more than 180 days in any year ) is there any holiday limit in overall span of 5 years?
2) is it necessary to have 5 yrs employment ??(or just last 12 months )
3) is there any maintenance requirement?
4) if there is CCJ on my credit history , which happened due to id fraud back in 2010 , will it effect my ILR, i never declared in any of my previous applications , i didnt knew about it till last year ?

sorry to ask all at once , but i might still have questions , please help .
