CD Project has commented on the save imports but nothing is confirmed yet. Anyway, here are some vague points:
- Some quest- and major decisions will be carried over according to your past choices
- Characters might react differently to Geralt depending on you completed TW1 (1)
- Importing some of the weapons and armor (2)
- It will impact the story, though not in a way that it changes it completely (2)
- It will not import your money from TW1 (2)
As sjohnston stated, if you manage to stun an opponent, you will be able to perform a so-called finisher move on him.
The probability of landing a finisher move depends on the chance of causing a critical effect, in this case, stunning.
You can view your chances of causing critical effects in the character panel (enter meditation and select "Character" from the radial menu)
The odds can be raised by getting or improving the appropriate skills, acquiring new mutations, drinking potions and using oils.

From http://witcher.wikia.com/wiki/Witcher_2_Ending not so clear answer to the question and still needs some editing.
Roche's PathEdit
-If you decided to kill King Henselt then the meeting in Chapter 3 will change a lot.
-If you let him live, Henselt doesn't only have Upper Aedirn but whole of Aedirn will be given to him as there isn't anyone left to ascend to the Aederninan throne because prince Stennis dies in the ghostly mist.
*If you went with Vernon Roche to save King Foltest's daughter, Anais, and you convince Roche to give the Anais to Temeria. Then Roche wil say that she decided to pick up a sword instead of a doll, and will be a great leader.
*If you went with Roche to save King Foltest's daughter, and you convince Roche to give the daughter to Radovid. She will grow up to marry Radovid and Redania will protect Temeria for the time.
_In the Epilogue, If you went to save Triss yourself, then on your the path to see Letho, You will see Roche saved Anais by himself and is defending her from a bunch of soldiers. You will save him.
Iorveth's Path
-If you decide to save Philippa Eilhart, then you will be able to release dragon from her control. You will not be given an option to kill her.
-If you decide to save Triss instead, then you will be given an option of killing the dragon or leaving it. Iorveth would've went to save Philippa and then get badly hurt by her. You will be given the option to walk away and leave Iorveth to the troops, or attack them and tell Triss to save her. She will say that he is badly hurt and will take months to heal him.
Shared Choices
If you saved Sheala de Tancarville, Letho will mention she will be hunted by Royal witch-hunters and die a slow death by them. If you let her die, then Letho will say you showed her mercy.
In both paths, if you save Triss instead, the Council of Sorcerers will still be created, since Triss is the one that pointed out Sile was the traitor.
If you did not save Triss, she will be saved by Lethos, Shilard Fitz-Oesterlen will point out Sile as the traitor and the Council of Sorcerers will not be created, as people will be hunting witches from then on.
Ending Sequence
If you go with Roche/Iorveth in Chapter 3, then you will walk out with Roche/Iorveth and Triss.
If you go with Triss, you will walk out with Triss only.
