help in british citizenship application

[babbal_samrat]

Hello All,
i have indian passport,
i have ILR in my indian passport. I have had ILR since Aug. 2008, my this passport expired in 2012, and i renewed my passport from Birmingham indian counsulate. but my ILR still remained in my old passprt. i did not transfer it to the new passport. The ILR i received was on the basis of me getting married to a british national. (we have been divorced since 2018).
i never applied for Biometric residance card / permit.
but now i would like to apply for british citizenship.
I would like to know a few things please...
1. do i have to have a biometric residence permit / card before i apply for british citizenship. or can i apply citizenship as i have my ILR since 2008 without having a BRP.
2. i was caught shoplifting in november 2009. i was given a caution by police for this. do i have to declare this when i make application for BRP or citizenship. will that affect the decision. i have had an extended CRB / DBS check done in 2019, and it came clean. there was nothing mentioned on it.
can you please get back to me with the answers, i will very much appreciate that,
