Visa supporting documents

[mm123]

Hello again.
I am planning to apply next week.
Apart from the documents listed on UKVI I will be submitting my degrees, my registration certificate as dentist ( India and UK both), contract, offer letter, Accomodation letter , cos details ( my visa consultant asked me to do so).
He has also asked me to provide salary slips of previous months ( though its been a while I left the job) but still I can arrange them as a simple receipt paid in cash because my boss actually used to pay in cash because it was small practice ( but he isnt satisfied with that).
He also asked me to keep some of my dad's document to show that he can also support me whenever i need it.
Is this normal? This is my first time. I want to know do you guys also submit these many documents?

Only submit what is required. Any additional unnecessary documents will be ignored or create confusion.

Thank you so much for your reply.
My father's document and salary slips arent actually required? Correct?
