I am applying for the EEA3 as EU citizen. I just want to make sure I qualify for this before I send my documents. I called their helpline but not very helpful

I am Bulgarian citizen came to UK in Sept 2006 to study.
Applying as EU from Sept 2006 to present.
For the duration I have been working part-time and full-time and finished my Bachelor and Masters (still one module so technically a student, but working full time)
I have the Blue card Residence Certificate and no restriction of employment, for the whole period of the years I have been employed only with 2-3 month gap.
I have all my P60s from 2006 up to now with my addresses on them.
My worry is that I am missing some of my tenancy agreements from 1-2 addresses but they can be confirmed from my P60s and payslips. Do you think this would be a problem?
Also do you know how long it takes for EEA3 form for EU citizen to be approved?
Thank you
