What will be the words of the disbelievers just after they will be raised up from their graves?

Verses 51-52 of Chapter 36:

Will God reward or punish on the Day of Judgement even  for the ongoing effects of the good or evil deeds people did before their deaths?

Did God promise the Paradise only for one out of the three groups of people who have initially accepted His religion?  

Verses 32-33 of Chapter 35:

Then We have given the Book for inheritance to such of Our Servants as We have chosen: but there are among them some who wrong their own souls; some who follow a middle course; and some who are, by Allah's leave, foremost in good deeds; that is the highest Grace. Gardens of Eternity will they enter: therein will they be adorned with bracelets of gold and pearls; and their garments there will be of silk.
