When you use your SB700 in SU4 mode, you are putting it into its dumb mode. It will fire whenever it sees any other flash, and it will fire at only the power you set on the SB700 itself. It will not get its power setting from the D7000.
The reason it is not sync'ing with your D7000 is probably because you have the flash on the D7000 set to TTL. In TTL mode, there is a monitor preflash, which is used by TTL to figure out the power required for the built-in flash. This preflash happens before the shutter opens, and is probably firing your SB700 before the shutter opens.
So, my recommendation is to put the SB700 into Remote TTL mode - NOT SU-4 mode. Then, it will use its own monitor preflash to determine what power it should be set to and then fire all automatically.
