Macau and Hong Kong Ferry

Hi,
we would be arriving in HK and from the airport itself we are planing to go to Macau on ferry, So please let us know the following
1) how many ferry terminals are there in Macau, I mean do we have to get down on a specific ferry terminal.
2) And on arriving back to HK from Macau, which ferry terminal we should get down as our hotel is in TST.
3)Can we get mobile simcard from the airport , will the same sim will work in Macau and HK. And how much will it cost to make a call to India using it.
Thanks a TON
