Ok, I see some major differences in the way JW's believe here.
I was with you until here. Why do people make up stuff when it is clearly explained in the Bible? Crucifixion was a common form of Roman capital punishment. Where did the stake idea come from?
You missed the part where Jesus spent 3 days in the heart of the earth ministering to the righteous who were held there until his arrival. Then he was resurrected after 3 days and ascended into heaven.
Ok, you're doing good here until...
Ok, first of all, the 144,000 that are mentioned in the Bible are clearly identified as Jews who will be 'sealed' until the end, to witness to the world of God's impending return.
The surviving righteous people of the 'end times' will be part of the Millennial Kingdom. The believers will not be resurrected in their old bodies, but will be granted new bodies... like Jesus had when he was resurrected (walking through walls, instantaneous travel, etc.

). The believers will help rule in the Millennial Kingdom.
The Earth is not the final disposition of man. After the 1,000 years and Satan and the final group of unrighteous people are finally dealt with, a New Jerusalem will be constructed after the old universe 'burns with a fervent heat'.
The 'Lake of Fire' is Satan's & the fallen angels final disposition, and 'outer darkness' is reserved for the unrighteous, where 'there is much weeping and gnashing of teeth', and 'the canker worm dieth not'.
It's unfortunate at how much division there is on God's word.
Yeah, these guys are going to think we're crazy.
