Electical Question- Wiring a relay

#1
Ok, so I got a set of XK Glow rock lights (http://www.xkglow.com/10_Pod_60_LED_4x4_Off_Road_Vehicle_Rock_Fender_Lig_p/xk061001.htm) for Christmas I want to run a relay and a switch... So.....I have a relay that has a 30, 85, 86, 87 and 87a posts. Currently, I have it wired like this:

30 to battery
85 to Ground
86 to switch
87 to lights...
87a is not hooked up.....should it be??

The Switch has three wires,
Red to 12v (Spliced into the 12v Constant on my Stereo)
Black to Ground
White to 86 on the Relay

Does that seem right to everyone?

Also, I want to wire in a Relay for my CB

Since there is not a switch, Would I wire it up like this:
30 to Battery
85 to Ground
86 spliced with 30
87 to CB?
87a not used?

Id like the CB to shut off with the Jeep.
Is it possible to have that happen but also have a switch wired so in an emergency I can turn on the CB even if the Jeep is off?

Thanks!
