So I move to Singapore mid May having never been to the country before (yes I am either crazy, brave or downright stupid

When I arrive my new company is going to put me in temporary accommodation for the first few weeks so at least that is sorted.
However, what I wanted to ask.... when I arrive I have about a week to 'settle' before starting work. Can anyone suggest what I should do first, best order or even where to get started!
For example I'll need a bank account and to pick up my work pass from MOM. But can I get the bank account before picking up my work pass (or before having a permanent residence). So things like this I don't know. Or should I just say screw it and spend the early days sightseeing!

All tips greatly appreciated!
