You will probably need tripod, lighting, good Macro lenses, soft box - and on the list goes.
Go check Adorama and B&H. See what's available pricewise and read the reviews.
Adorama also has some kind of forum.
Plenty of forums, too.
Digital Photography Review is one. They have a forum for just about any camera
Photocamel isn't too bad either.
There are many others that are camera specific.
