The noise environment for interconnects is VERY different from that for speaker cable simply because interconnects carry smaller voltages.
If you are going to run long interconnects, then using balanced interconnect cable is likely the way to go presuming the devices at either end of the cable do the right thing with that.
I still agree with Bob, but suggest the OP do more research to satisfy himself on the best approach. This issue has been debated forever and there are lot's of gut feel comments and unsupported statements floating around (not suggesting that's the case on this forum, just in general) I would be especially wary of comments from retail sales guy's who may have limited or no actual technical knowledge of the facts and will use lot's of wonderful audiophile descriptions.
Since he already has the speaker cable installed, I'd suggest trying it with short interconnects and see how it sounds. Perhaps you can borrow some long interconnects and try a comparison, recognizing that it's always difficult to reliably compare cables.
