aisay,
dun lose hope so quickly...thts a nice car u have right now.
Am not sure abt the auto shifter button but i have a spare a31 auto shifter...if its the same u can try using it. As for you handbrake light, its probably just the wire from the bottom of the handbrake or the handbrake switch...small problem.
Draw out a plan on what you need to get and what u absolutely must get and work from there. Alot of potong shops all over...puchong, subang, salak south....ask cmng, he should be able to reply you on parts, etc.
cheers
