re-confirming details- premium visa - ILR

[hamzababy]

Hi all , just need to reconfirm what i think i already know but need expert reassurance that all is in order.
Spouse Visa route 5 years.


Entered UK 22/09/2013 .... Eligible date for ilr- 26-08-2018 ( 28 days early rule ) can you please confirm this is right date for eligibility.

life in the uk and english test , both done.

6 months payslips in progress and corresponding bank statements and other bits n bobs like , letter from parents for providing accommodation, bills , baby's passport , random pics etc ...

how early from my eligible date can i book a premium appointment at croydon home office.

i heard there is waiting time now for over a month , last time when i had extension done on my flrm , dates were always available so a bit confused , as to how early can i book for 26th august 2018.

while at it , what would you suggest after ilr approval , should i apply for passport via online service or by post..


Regards...
Thanks for help in advance ...

i heard there is waiting time now for over a month , last time when i had extension done on my flrm , dates were always available so a bit confused , as to how early can i book for 26th august 2018.

sorry i just figured out i can apply 28 days before my qualifying period so that would be 29-07-2018 ,

since i will fill all my forms at this stage on 29th july and will input my annual gross salary ( well above £18,600 ) but always varying , would i take payslips upto july with me at the appointment on 26-08 because my calculations will be done on payslips till july , or the latest payslips upto august.

my salary varies sometimes between two payslips depending on if i take day/days off or do extra work. so i dont want to give wrong average figure... or if it does vary , i can just take new payslips and explain to them over counter ? thats if they do let applicants change details or let them explain things over the counter , usually they are too busy...
