Hi Niki,
I had my LB at Genesis 2 years ago - had to have a c-sec though.
During my entire pregnancy I only saw a gynea 3 times. For the important scans, at 13 weeks and 20 weeks, and then a last checkup at 36 weeks. I saw the midwive in-between for check-ups.
I used Dr Mia for as my back-up gynea (and he did my c-sec in the end), great gynea, but VERY busy. Dr Maasdorp was assisting him at that point, and I saw him for my 36 week check-up (Dr Mia had an emergency c-sec - literally ran out the door as I was about to walk in

).
I personally liked both of them, no negatives at all

. Even though Dr Mia was very busy, and his appointments were running late, he still took his time. He talked to us, answered all our question, took his time with the scan, explaining everything as he went along. I think my one appontment lasted nearly an hour!! and this with a full waiting room.
1 & 2. I know there are moomie's that have seen them (and the midwives) a lot more recent than me, so I will leave the recommendations up to them
3. At your 36 week checkup, the gynea need to give you an all-clear for natural birth. If there are any concerns at this stage, they might refer you to a hospital instead (they only do low-risk births, as they dont have a NICU). Also, if you go into labour ealry (think its before 36 weeks, but just confirm) you should also go to the hospital instead.
If you labour at genesis, and end up needing a c-sec after-all, they will do the c-sec at genesis. They have a fully equiped theater on-site. If baba needs to stay in NICU for any reason, they will stabilize baba at genesis, but then transfer to Parklands (which is apparently very close).
