Get this kit if you don't need a flash:
Strobist Starving Student SC2 lighting kit (no flash)
Get this kit if you want an extra flash:
Strobist Starving Student SC1 lighting kit
If you want an extra flash then you'll need an extra receiver here:

Now this is if you wanted the Cactus v2 triggers. I'd highly suggest you get the v4 triggers instead if you can.
So if you get the v4 triggers then you'll need this:

and this:

You need one receiver for each flash. The basic cactus trigger kit comes with a transmitter and a receiver.
I'd email them and ask them if you can switch out the v2 for the v4. They're pretty nice people and they know what they're talking about. I've bought things from them in the past.
If they wont' switch out the v2 for the v4 then just get one of these kits:
Strobist Starving Student SX1 lighting kit (comes with flash)
or
Strobist Starving Student SX2 Lighting Kit (no flash)
You won't really need the PC cord but it can be used with your camera for other things if you get a hot shoe adapter and want to hook it up to some studio lights.
