Stroller, baby advice welcome

Dear friends, now that our apartment move is complete, we can start thinking about preparing the nursery and baby stuff. Please comment if you have feedback on some of any of these topics below.

1) Strollers. As we are 'city folk' and don't have a vehicle, do we need an infant carseat/with frame, in addition to a normal lightweight foldable stroller? For the latter I hear the MacLaren Quest is a good model for 6 months - 3 years but it doesn't lie flat

2) Crib. Are drop side cribs OK? I know they're banned now from US/Canada but they are still sold here in HK.  Also I read that firm mattresses are better and safer for the baby

3) Bottles. I will try to breast feed and my sister gave me a breast pump already. What type of bottles, nipples, storage solutions are best for breast milk? We have a Dr. Brown bottle sterilizer but I'm still looking for a bottle warmer and few more bottles/inserts/nipples

4) Schools. Do we already have to register/apply for our unborn baby to join some HK international schools? (I wouldn't be surprised; my admin told me to rush on this)

5) Baby monitors. Are recommended brand? We also need a nanny-cam if you know of any good ones.

6) Rocking / feeding chair. I'd rather buy a lazy boy or something similar. Anyone know where to find this in HK?

7) Sling and/or baby carrier. I already have a Baby Bjorn Synergy. Do I also need a sling, and an Ergo Baby carrier for later?

8) Baby bath - is the infant insert essential? What do you think about inflatable bathtubs (space saving :))

9) Swings - good or bad?  I have read both.
