Hi Sangha,
I am in no position to say whether Pure presence is nibbana. I can only write from my own experience and understanding.
This pure presence is called Rigpa in Tibetan Buddhism. I am not a Buddhist in this life, but I was a Tibetan Monk of Nyingma school several lifetimes ago. That is why I still have a lot of interest in Buddhism.
About Rigpa, when we experience it. It is formless and empty and at the same time infinite and all pervading. It is NOT BLISS. Bliss is a samadhi state but it is not the true nature yet, it is still a state in the mind. I have bliss experiences also, in fact i have then now quite often outside of meditation also.
Rigpa is a presence of 'yourself' that is connect to everything in the universe. That is probably why the Buddha say that there is 'no self'. All is connect to all in the Dharmakaya. Rigpa is a part of the Dharmakaya. When in the state, there is no separation into you or me... We are all one thing which cannot be described.
However, I must say that even now, while reading this, we are already the rigpa. We do not realise this is because we THINK we are just the mind/personality. The mind/personality is a REFLECTION from rigpa. It is not the true self. If you understand what I am write, you may get a sudden awakening/realisation. And if the realisation is deep enough, your viewpoint or way of seeing the world will change.
Just my 2 cents...

Jhana is attained with no expecting, with no wanting, with no not wanting, with no unawareness, with no thoughts, with samadhi, with mindfulness. Only a mindful mind is a ready mind for meditation.
Jhana starts from within, it is a state of focus mind. It is still impermanance. But is is free from craving. A craving (aversion and attached) mind will feel discomfort when attempting to enter Jhana.
When one enters into Vipassana after Jhana, it is a process of noting rather than thoughts. We need to even note of defilement thoughts.
When one is in 4th Jhana, he is also in equanimity, or what u called Upekka. a state of no craving, no happy, no sad, no hatred. And left with one pointiness.
"Pure Pressence"? Are you referring to Nibanna? The Buddha's natural that everyone has?
Buddha ever said, even when He was in 8th Jhana, there are still 2 things available, which is perception and feeling. This means that Jhana is not Nibbana.
