1., 5., and 6. should be done at official/authorised service centres
The rest can be done elsewhere, preferably by people who have been dealing a lot with the specific task like servicing the turbo. Search facebook for people like Zainuddin Jasman, Tam turbo, etc in the cfe/cvt group.
For the oil catch tank, you've got a choice of buying one online for a much cheaper price and either installing it yourself (which is really easy to follow), or getting someone to install it for you (and buying if you don't want the hassle of sourcing for the part)
Side note:
And sorry, but if someone is running a business or are related to the person, there's no need to act like they don't know them. I find their labour cost to be over the higher side compared to other more popular shops, so unless distance is a problem, look for those people mentioned via facebook
