Question about HTIB

Hello,

I have never had a home theatre before and I am totally new to the av field. I'm here to request some kind advice.

I have a tight budget(~$500). And for the same reason I wanted to go for a HTIB option (something like Sony BDV-E780W). And then I researched a couple of other options. Finally, I ended up with:

Energy 5.1 Take Classic (~400 - I selected these speakers coz of the price and excellent reviews)
Onkyo TX-SR309 5.1(~185 - Selected coz of again price, decent reviews and 3d pass thru)

I am going to buy a 3d tv (47LW5600), and the above av receiver was the cheapest I could find with 3d pass thru and decent reviews.

So, here are my questions:

1) For my budget, should I still go for an HTIB option or should I go for something like Energy+Onkyo? (In terms of features for money? - Sony has wireless rear speakers)

2) Please let me know your feedback on the combination of speakers/av I have picked? My main source will be blue ray player and ps3/xbox. I won't be watching much tv programming as I am not from here.

Thank you.

@afrogt: Thank you for the response. I definitely feel 509 is a better choice.
Any words of wisdom on the speakers? Can you recommend a cheaper set delivering same quality if not better?(~$300)

Thank you so much again for taking the time. The nearest Fry's is 3 hours away but I am totally ready to drive if it's really worth it. I just saw those speakers on amazon. They only had 2 reviews vs 180 for Energy. Again, since I have no clue of these systems(or av on the whole), I am just relying on the reviews. And looking at the Jamo reviews I was a bit concerned. Do they deliver the same quality as Energy?
