Use car washing towel rather than a chamis, most of these will hold more than their weight in water and are super absorbent. Dry the bodywork of the car using small circles to avoid streaking.
If your car fails first time do you have to pay for the second retest?
Yes.

I would find a better garage!
Which is cheaper then have your garage pre inspect it!
It depends on what the fail was for. If it is something simple like a duff lamp, or windshield wiper missing then it is no cost. Basically, if the car doesn't have to re-enter the hall then it costs nothing.
Having the car clean is important, detailing it is a bit over the top. Regardless of how clean the car is, a failed safety item is still a fail, but as a general rule, the dirtier your car is the closer they will look for minor issues.
