Brake System Rebuild - Planning Ahead

Alright, well I figured I might as well just completely rebuild the brakes. I'm looking up parts, it looks like I'll need:


The bearings and all seemed to be fine, so I don't think I'll replace them.

Did I miss anything?
Where could I get lines from?
The adjuster repair kits on RockAuto, does anyone know if those come with the parts for two wheels, or just one?
Will I need to get a different pushrod for the MC since I'm going from a single-chamber to a dual-chamber?
