“What are those dhamma that have annica and dukkha nature?”
None other than sankhara. Only sankhara have the anicca and dukkha nature. All sankhara eventually lead to dukkha and thus have the anatta nature too in the sense of becoming helpless. If you think there are, you can list them and we can discuss. Remember that anicca is a perception in the mind.
Everything else is dhamma and anatta in the sense they are also not fruitful in the end. But of course, we do need Buddha Dhamma to attain Nibbana. Once the Arahanthood is attained, there is no need of that either, and that also needs to be abandoned. This is why the Buddha said just like a raft enables one to cross a river, but no point in carrying it once the river is crossed. Some who get to the Anagami stage have a hard time attaining Arahanthood, because of their attachment to Buddha Dhamma.
Of course, there many other things that are included in “sabbe dhamma” category, including nama gotta (records of all sankhara that have come and gone to the past).
The key is that sankhara are CURRENT thoughts. As soon as those thoughts expire, they become nama gotta. This is something that most people do not understand. This needs some contemplation. But you are on the right track. I have explained this in detail in the post, “Pancakkhandha or Five Aggregates – A Misinterpreted Concept” and “Pancupādānakkhandha – It is All Mental“. I don’t think that many people have read those posts. They are not an easy read, but necessary to understand things better.
You may want to take a break for a couple of days and then go over things again. You may be putting too much effort into this in a short time.
