I ran into this while looking for stuff on Rove and the 2002 elections. It doesn't touch on any of the dirty business, of course, but it gives a pretty clear general picture of what was being done, to what ends, and by whom.

The White House is running the earliest, most elaborate political operation in 20 years, reaching deep into key campaigns across the country.
The effort was launched at an organizational meeting before President Bush's inauguration platform had been torn down. It is designed to elect Republicans this fall and lay the foundation for Bush's re-election in 2004. The operation is patterned after the political work of previous administrations, but the preoccupation with politics and Bush's re-election permeates the White House to an extent unrivaled by recent presidents. . . .
An informal command team, which includes officials from the White House, Republican National Committee (RNC) and congressional campaign committees, was created to manage the operation. The team identified key races and handpicked candidates, sent operatives to help run campaigns and is orchestrating fundraising.
Running the show are a few strategists, including White House political director Ken Mehlman, RNC Deputy Chairman Jack Oliver and Mike Stokke, deputy chief of staff for House Speaker Dennis Hastert. Karl Rove, Bush's top political aide, doesn't attend the meetings, but he oversees everything.
