First, you might want to read through the articles by the Vinyl Anachronist. He does a great job of explaining how everything works and what you need to set up a turntable.
I'm not sure what the exact model of cartridge you have is. It might be an AT; the best way is to look at the cartridge itself for markings. It should have something to identify it on its body.
Nikongod is correct about receivers. You have to look at what's included in the total package. Like he said, a receiver can just be a radio tuner. However, those are usually called a tuner rather than a receiver. Most of what's referred to as a receiver has a preamp, amplifier, tuner, and sometimes a phonostage built into one box. It might seem confusing, but you need to think of each element as a separate component.
You have preamps, which include a volume control and the ability to select between different sources.
You have amplifiers, which take a signal from a preamp and make it more powerful, so speakers can be driven.
You have a tuner, which tunes in AM and/or FM signals.
You have a phonostage that provides the RIAA equalization to make records sound as intended.
Now, all four of these things are available individually. I have a separate preamp, phonostage, tuner, and amplifier. Some manufacturers put all or some of them into a single box. That single box is usually called a receiver. You will also find integrated amps, which usually have a preamp and an amp built into one package. Sometimes the integrated amps have a phonostage, too.
When you look at the chain of components, you need to connect speakers to a power amp. Since a receiver has a power amp built in, you connect the speakers to the speaker taps on the back. The receiver also has a preamp, so you can connect a source directly to the receiver.
If you have separate components, you'd connect the source to the preamp, the preamp to the power amp, and the speakers to the power amp. Since a receiver has all of those components inside, you can just connect the source to the receiver and the receiver to the speakers.
