Biblical basis for two aspects of the Gap Theory

According to the [Gap Theory](http://en.wikipedia.org/wiki/Gap_creationism) there was a large gap in time between Genesis 1:1 and Genesis 1:2. Two aspects of the theory are: 1. Rather than Genesis 1:1 being a summary for what follows, it is a distinct event in time, followed by another distinct event in time in Genesis 1:2ff. 2. Satan is thought to have sinned and fallen during the gap, which God judged through a cataclysmic flood (often called Lucifer's flood) that left the world in the empty and void state we read in Genesis 1:2. What *other* verses in the Bible support these two propositions?
