Mike,
The handbrake cable goes in from the back of the car forward as shown below, the handbrake shoes are self adjusting, there is a cam mechanism at the top of the drum setup than when you pull on the handbrake it will automatically adjust the shoes.
The rear brake lines are tight against the uprights, but mine can be moved slightly, however they are just touching. One method I used for installing them was to loosen the bearing hub from the rear upright slightly so that you get around an extra 10mm of clearance and then you can fit the handbrake cable and rear brake line with ease and then you can tighten them up again, however you need to watch to make sure you dont damage anything when you tighten them up if there isnt enough clearance. I have known people to have to slightly modify their rear uprights to allow enough space for the handbrake cable to fit
