Revelation is a pretty tough one! But everyone who even reads it will receive a special blessing. (Rev 1:3)
A lot of the stuff at the end of the world is kind of controversial -- in how it is interpreted. For Example: There are people who believe that the Tribulation comes before the Rapture (that is, a post-Tribulation Rapture), which means that Christians would go through the Tribulation , but most believe in a pre-Tribulation Rapture (Christians are gone before the Tribulation-- except for the 144,000 who remain behind to lead others to Christ -- called the Remnant).
Judgment Day is another controversy at to whether "everyone" will be judged or only those who were not born again. I've always believed that Christians would also be judged but recently heard teaching that we will not go through this as we have been forgiven. But even if Christians are going through Judgment Day, they will not die the second death, nor will they go to hell or the lake of fire.
Generally, the "second death" refers to what people who are not born again will suffer -- and that is when they are cast into the lake of fire. (Until Judgement Day, those who are not born again are in hell, which is bad but apparently different from the lake of fire.) They first have the physical death (when they breathe their last breath on earth) and then the second one (when they are cast into lake of fire).
Born-again people will only suffer the one death -- the physical one. The born-again who experience the Rapture will not even experience the one (physical) death.
David Jeremiah gave talks about Revelation in the last year or so. You can probably find info (and play the radio shows) on his website, DavidJeremiah.org .
