ILR for Teir1 general Category - documents Required for self

Hi ,

Thank you very much for your information , it’s very helpful .
I am also planning to apply for ILR in this September but I have few doubts/questions for my case

First question :
I have got my VISA (Initial Teir1 general )approved on 6th October 2010
My first entry to England was 28Th December 2010 (approximately after 86 days of my Visa approval , this is within 90 days )
Now my doubt is can I apply for my ILR on 15 September 2015 or I have to wait till December.

Second question : do I have to provide details about all my visits outside UK for this last 5 years ?? , although I had very few that too far very short durations .

Third Question : During my initial application , for English language eligibility I had used PBS calculator provided by UKBA site to show my University was listed on their calculator , but now there is no category for Tier-1 general hence there is no calculator .. what should I do for English language eligibility ??

Do you guys have any templates , sample cover letters for all section of these documentation .
