My daughter was born exactly 6 weeks early and weighed 4lb 13oz. She was initially taken straight to SCBU. She wasn't breathing when born and needed 'extensive rescusitation' so that was why. If baby is breathing and screaming when he comes out you will get a chance to say hello before he is taken.
The most likely problem initially will be keeping the temperature stable so he may be in n incubator. He will have a feeding tube in either his nose or mouth going to his tummy, and he will probably have his arm splinted with an IV for antibiotics as your waters have been gone a while.
It will take a few days for him to establish feeding. They tend to get tired very quickly at that gestation.
My daughter was out of an incubator the same day as being born (she was born early hours of the morning) and out of SCBU and with me on Transitional Care within 36 hours.
We managed to get breast feeding going very well and came home on the evening of day 6, against medical advice so by all accounts expect to be there for at least a week or two.
Basically you can't rush baby, and they do what they, when they are able to do it.
Have you had steroid injections for baby's lungs? That will improve the chances of him not needing cpap when he is born. If cpap is needed, it probably won't be for long.
