It's true about the similarity of Goblins and Dwarves in that they craft something the other races cannot etc. But from my point of view, the Goblins of Rowling are more similar in their nature not to the typical Dwarves we know (like Thorin and Gimli and all these folks), but more (and it's the same with the House-elves and so on) the folk oppressed or overlooked by the other races, like the Petty-Dwarves (quite a lot, I think), or even the Drúedain.
Hmm... looks like while avoiding spoilers, I cannot write much more I would say... but I think I said the main things I wanted.
And also - well, I think you can see something similar to Tolkien's Goblins in Rowling's Goblins anyway. Sometimes, just sometimes. Again, in the chapter "Shell Cottage", there is mentioned that even Rowling's Goblin could be unexpectedly bloodthirsty, to laugh at the idea of pain in lesser creatures... then perhaps they could be compared to Tolkien's Goblins, even Orcs.
