As long as the humidity in the viv is ok, you have nothing to worry about. And if you have a good sized water bowl and your temps are good, it's likely your snake will shed just fine.
Signs of imminent shedding: A secretive and/or grumpy snake (you might not see them at all for a week or more), or alternatively you
may see them bathing, dull skin and cloudy eyes. This is what they call the 'blue' phase. A few days after the eyes have cleared is when the snake will shed.
You will know immediately if something has gone wrong, as you won't have a complete shed to remove from the viv! Very likely you'll be able to see 'peeling' skin on the snake too.
All you have to do is check the shed skin. Make sure the eye-caps are there (not two holes) and the tail tip has come off.
IF the shed is incomplete, then you can use the moist paper towel or bathing method to help finish the job. There are lots of threads on here about it, I'll find you some good posts if you need them. Another good thing would then be to make a 'moist hide' or 'mist' (spray water) in the viv in the days leading up to a shed.
This is only necessary if you have problems, so do some reading up if you like, but I'd recommend you just wait and see how things go first
