1: could be the switch inside the car.. or the LKM.. fuse, wires connector, common ground....
8: sounds like the heater core valve is stuck open, i hit mine with a hammer a few times and it seems to have mostly closed, do a search for a thread i started on it, there is a link to another thread which has teh fix
4: in addition to the valves, i think there is something relating to the camshaft something bolts coming loose. after the valves are done, and the bolts solid, take a look in the engine. if it looks filthy, order some Auto-RX (if he ships to the UK) and run 2 rinse cycles. then after, switch to synth oil and run lubro moly MoS2 oil additive.
9: might as well grab some Alpina seats somewhere heh.
