I ordered some of these a few days ago and have asked similar questions via e-mail. Ben will reply when available .. but for now here are some details I have from e-mail(s).
First .. Ben is very responsive and it was sent to shipping quickly on their side. I'll let you know how long it takes form me to get it here in Florida .. may give you a rough idea .. but it says 4 to 10 business days (better than from China on e-bay usually).
Yes - Every module is fully addressable (can be controlled individually).
If you are looking for something like 6 inch instead of 3 inch spacing .. the Domes ".. .can be strung approx 17cm apart" per an e-mail. So that may fit the bill as is (and water proof).
When I get my order .. I'll post a full independent review (not affiliated with Bliptronics).
Good luck with your coffee table
