Hello Nemo, welcome to this Website!
You asked:
Which Bible is viewed as the most accurate?
From the research I have done, I would definitely without a doubt say the King James Version and any other Translation based on the Textus Receptus and Majority Text instead of Westcott and Hort.
I recommend checking out http://www.e-sword.net and http://www.blueletterBible.org
Do we all go to heaven, is there a hell?
In my life, JESUS has the final say about everything, so I will let Jesus answer your questions:
John 12:26 (New King James Version): If anyone serves Me, let him follow Me; and where I am, there My servant will be also. If anyone serves Me, him My Father will honor.
John 14:2-6: In My Father's house are many mansions; if it were not so, I would have told you. I go to prepare a place for you. And if I go and prepare a place for you, I will come again and receive you to Myself; that where I am, there you may be also. And where I go you know, and the way you know." Thomas said to Him, "Lord, we do not know where You are going, and how can we know the way?" Jesus said to him, "I am the way, the truth, and the life. No one comes to the Father except through Me. Luke 16:19-31: "There was a certain rich man who was clothed in purple and fine linen and fared sumptuously every day. But there was a certain beggar named Lazarus, full of sores, who was laid at his gate, desiring to be fed with the crumbs which fell from the rich man's table. Moreover the dogs came and licked his sores. So it was that the beggar died, and was carried by the angels to Abraham's bosom. The rich man also died and was buried. And being in torments in Hades, he lifted up his eyes and saw Abraham afar off, and Lazarus in his bosom. "Then he cried and said, 'Father Abraham, have mercy on me, and send Lazarus that he may dip the tip of his finger in water and cool my tongue; for I am tormented in this flame.' But Abraham said, 'Son, remember that in your lifetime you received your good things, and likewise Lazarus evil things; but now he is comforted and you are tormented. And besides all this, between us and you there is a great gulf fixed, so that those who want to pass from here to you cannot, nor can those from there pass to us.' "Then he said, 'I beg you therefore, father, that you would send him to my father's house, for I have five brothers, that he may testify to them, lest they also come to this place of torment.' Abraham said to him, 'They have Moses and the prophets; let them hear them.' And he said, 'No, father Abraham; but if one goes to them from the dead, they will repent.' But he said to him, 'If they do not hear Moses and the prophets, neither will they be persuaded though one rise from the dead.'"
