Deepak Welcome
I can help you with a couple of your questions and I'm sure others will jump in soon with more advice.
You can go to the factory outlet and get any system you want, and I beleive if you order 5 items you get an additional 5% off. There is no difference in the outlet products from the new products other than they may or may not have a blemish, I could never find one on mine.
As far as receivers go you can find many good receivers in the $300.00 to $500.00 range that should more than meet your needs. If you have a paticular budget in mind for a receiver I'm sure you will get many suggestions. Again welcome, and have fun with your choices.
