Relax. It is also the position of many amills and many postmills.

You are starting in the wrong place. You are making the same mistake which Spurgeon made. (Remember: Spurgeon did not know what to make of the position of the heretical full preterists. He really was confused.)
Before you start tackling the details of millennial prophecy, you need to figure out what the millennium IS.
And the passage which defines the millennium is in ONE place in the Bible. And when we let clear Scriptures interpret more obscure Scriptures--which principle, of course, is one of the most important principles of hermeneutics--we discover that John 5 is the clear text which interprets Revelation 20.
Furthermore, John 5 does not merely offer amillennialism as an interpretive option for Revelation 20. Heck, John 5 demands it. John 5 flatly contradicts the premillennial position.
The reason why Spurgeon was so confused--even to the point of endorsing Russell's book as interesting and harmless--is because he never noticed all of the implications of John 5.
Rev 20:4 And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.
