i can only give u lists of what i know in kuching not sarawak. sarawak is huge. the list of schools u listed are the main ones. there are quite a number of smaller schools but those u listed are recommended as theyre more established. theres one called mass music thats along jalan bayor bukit (just go straight from tabuan jaya). i dont know much about that school.

if you're looking for a school that caters for chinese musical instruments thats good, u can try Kenwy Music House. im not saying this because it was opened by a friend of mine but ive seen them play and theyre very good. i know a couple of instructors there. u can try contacting them at kenwy_mh@yahoo.com or visit them at 904, 1st floor, tabuan jaya shopping centre, 93350 kuching, sarawak.

for vocals how about private vocal tutor?

ask around. alot of private tutors in kuching

i almost recommend u contacting ....YOU. lol.
