401k Rollover limitations?

I am retired and 65 and have 401k and TRAD IRA with some basis

I am thinking to take funds out of 401k,  but instead of paying full taxes on it, wonder if I can rollover the amount to my TRAD IRA, then take the withdraw from there and pay a bit less taxes on it this year

 

1)  Does this work or are there any issues/concerns?

2) I heard about the 1 year rollover rule, will that impact/limit this approach?

3) I also heard about Direct Transfer from 401k to TRAD - what does that mean and is that a better option?

thanks
