The belief of a restored paradise earth was adopted by C.T. Russell from the Adventists. This is NOT an original Jehovah's Witness doctrine.
We, as JW's, are taught that during the 1000 year reign of Christ (actually the annointed Governing Body) we will be burying those killed at Armageddon, cleaning up the entire earth and teaching the true religion to all that Jesus and his annointed 'brothers' resurrect.
During this time we will have to work our way into perfection - a task that will take 1000 years to acheive. If we fail in this task, we will be destroyed forever at the end of the 1000 year reign - and our friends and family will live on for all eternity, completely forgetting about us and enjoying life "as it was meant to be".
Sounds awesome.
