In regards to the brake line I did't see where they were talking about, but I will prob just ziptie it out of the way. A lot of the repairs seem pretty easy to do from all the How To's on the forum and the videos on youtube. I have most of the necessary tools, just need to get an engine support and transmission jack.

For a clutch to slip so bad that it prevents the engine/super charger from producing boost, it would make the car almost impossible to drive. I'd be interested to know how a slipping clutch would prevent the Mini from producing boost...

If the harmonic damper fails, you loose EVERYTHING...so no alternator,no ac, no sc (if an s) but more importantly no waterpump...
Sounds like the alternator died, and you drove on as the battery got weaker...and weaker...and as the voltage got low...odd stuff happens...once the battery light comes on, it means the voltage is low...first to shut off (as intended) is the power hungry PS pump...then the time you can keep driving depends on the load (lights, etc) and how good the battery is...
