From what you are saying is that you have nothing at this point? Not even a TV? You can buy a 1080p 50" Plasma TV for under or around $1,000. From my experience, Plasma and light don't work well together, so I watch my Plasma TV, all my curtains are close. My brother have a LCD and seems to work a lot better in brighter situation. Stores such as Frys, Sears often run pretty decent sales on their TV. Go to bargain websites such slickdeals.net or fatwallet and keep an eye on sales.
You can buy an entry level Blu-ray player around $100 at many stores, including online like Amazon, vanns, 6ave.
Receivers go on sale often, again check slickdeals or fatwallet daily. Onkyo, Yamaha, and Denon go on sale often. You can get a good receiver in the $300-500 range from any of these brands I just mentioned.
From my research, most would avoid ceiling speakers for your main fronts. They can get by as surrounds. How many speakers are you planning to buy? Do you want a subwoofer as well? Are you open to others or are you set on just ceiling speakers?
You can buy all your wires, connectors, HDMI cords online from monoprice.com. Affordable, good products, and super fast shipping.
You don't need to overspend if you know where to look and keep an eye on items when it goes on sale.
