Moving to Bahrain

For the most part, you can browse the other threads to get an idea on cost of living.  I will comment where I can.

1) 200 Kg?   or do you mean a 20 ft container?   200Kg sounds pretty much like air freight.  If that is the case then it's probably better for you to get a furnished apartment or buy stuff here.  As if you bear the cost for shipping and insuring, it won't be worth it
2) Varies from apartment to apartment, no fixed standard.  The costs you can get an idea about on the sharaf dg bahrain website.  They would be reasonable
3) Around the Muharraq area or Amwaj would be the best bet for you.  As an expat, I would definitely suggest Amwaj
4) Public transport is buses and with very limited coverage; only started a few years ago.  The alternative is cabs which are very expensive or uber / careem which is more reasonable. To rent or to buy depends on your plans i.e. how long are you here for.  If you are here 2+ years, definitely buy as it would be cheaper and you can get a better car
5) Buying is either new / pre-owned cars through dealers or used cars.  The dealer angle is simple and they take care of everything.  Even if you take a loan, it's easy to coordinate with dealers.  Buying from individuals is more of a hit and miss and you can browse the classifieds on OLX for that.  The alternative is car rental or leases; the rent to own concept is generally not followed in these deals for individuals as it is too costly but companies routinely do that
6)  Groceries are definitely more expensive than your home country and at par with, say the UK or even more.  As pretty much everything is imported.  However, availability is good and fresh produce you can find from everywhere in the world.  From shops standpoint, these can range from the corner store to the large hypermarket
7) No you don't have to cover up.  This is not Saudi .   But be mindful of cultural norms and try to dress appropriately i.e. no beachwear in public places like malls!!
8) Potentially.  However, the economy is not good nowadays and you would have to look when you get here.  Browse the threads on this forum where job seekers have asked similar questions and I have given them a detailed breakdown of their chances
9) All of this information is covered on the threads in this forum.  Some links to help you:
