All you really need to get started is a receiver that outputs it's audio signal per channel between 30 and 400 watts at 4-8 ohms, and if you want to connect a PS3 through the receiver I would suggest getting a receiver that has an HDMI input (if not two). If you're on a tight budget you could look at the Insignia® receiver model NS-R5101, and you can take a look at this receiver here:

Without knowing what size TV you want I wouldn't be able to suggest a specific model, but I'm sure if you went to your local Best Buy® store they should be able to help you out! I hope this helps!
