Steve,
If you're saying that the Rapture will happen in Spring '08, and the Second Coming in 2018, then what will be happening in the world between the Rapture and the beginning of the 70th week (7 year tribulation).  The 70th week starts with the confirmation of the covenant, which you are dating in 2011.
Also, how would you tie in the much prophesied date/event of December 21, 2012?
