Help assembling a home theater system

[sockmodel7]

I was hoping on some advice on the way to go for a complete system, with speakers and receiver. Here are the options:

Front:
JBL L890
Polk TSi500

Center:
JBL LC2
Polk CS20

Rear:
JBL ES30
JBL L820
Polk TSi200

Sub-woofer:
JBL L8400p
Pioneer S-W1EX

Receiver:
Pioneer VSX-1917TXv-K
Harman Kardon AVR-354

My other option is the JBL Array line, but I'd likely only be purchasing a couple speakers at a time, since even at 50% they're still a bit pricey to say the least. Based upon my limited knowledge it looks like JBL across the board for selections, but I had hoped to get some other opinions before pulling the trigger.
