Is there an ideal date to apply for the FLR(M) to make sure I cover all the 60 months needed for ILR? Is ILR the same as SET(M)?

SET(M) is the name of the application form used to apply for ILR (it's Settlement based on Marriage to a UK citizen).
There isn't really an ideal date because the FLR(M) should be made valid from either the expiry date of the spousal visa, or from the date it is issued, if the visa has already expired.
However, if you want, you can wait until closer to the expiry date to give yourself the most amount of time. It's really up to you though, since FLR(M) takes about 2 months to be processed by post, so even if you apply in October, the visa probably won't be granted until December or January anyway.
