Larry - you are correct. That is exactly what is covered in that portion of Revelation. The FINAL death is that of the soul - for Satan ( who is already condemned to death) as well as his Fallen Angels and those souls who refuse to believe Christ's teachings during the millenium.
The 1000 years of teaching and learning which will take place during the millenium and which starts at the moment Christ returns at the Seventh Trump, will allow those who never had an opportunty to learn about Christ here on earth, to believe in Him and follow Him instead of Satan. It is written that Satan will be 'loosed' at the end of the millenium for a short 'season' and anyone who is still 'in bed' with him at that time will ALSO be cast into the Lake of Fire, which eliminates their soul from the eternity.
You can get all the "Hot News" in Revelation 20-22 (KJV).
