Serparate relay is a good idea with aux horns. Typically they draw more than the stock horn and you don't want to burn out your horn switch.
Aux lights with any sort of wattage should be switched separately and run through a relay was well. If you're just adding some LED "bling" then you could hook them into the existing.
Do a search on the modulator, there has been a fair amount of discussion and, I think, one of the suppliers is currently doing a closeout, with better pricing.
