I'd say the broken springs, torn torque tube bushes and engine mounts would be priority.
Everything else can wait. As for the various seals, that many leaks on an 80k engine suggests crankcase pressurisation, so I'd try and find the underlying problem, assuming there is one, rather than simply trying to fix the symptoms.
Broken bleed nipples will need doing eventually, but keeping the current brake fluid for a few months is unlikely to be a problem. The torn gaitor on the ARB isn't a problem now if the ball joint isn't worn, although it'll accelerate wear in the balljoint so it'll need to be done eventually, but you might as well wait until the balljoint goes. As for the corroded pads and discs, it depends how bad it is. If the car brakes OK, I wouldn't say it's a priority.
