Lots of good advice from the other guys. One thing I would add is make sure you label absolutely everything. Tie on labels are best - sticky ones tend to fall off. The electrics are particularly important to label.
I would also strip every nut, bolt fitting and bracket - its amazing what can come in useful later in the build.
