Hello Mike, Welcome to the Shack.
The 606 is a fine receiver, I prefer Denon (personal preference) but at this price point receivers from Yamaha, Denon, HK, Pioneer and Onkyo are all comparable. Right now Onkyo generally has a bit of an edge in performance/features/price.
As for HTiB vs. picking out a system,... depends on what your expectations are. HTiB may satisfy you, or you may hate it.
As for ratios,... I'd suggest you spend about 3:1 audio:video, so to get the most out of your new Samsung you'd be spending about ~$4500 - $5000 on your receiver, sub and speakers. Of course this does not mean "you" will not be happy with a $900 HTiB, again it depends on your expectations. Everyone has different wants and needs, some spend $5000 or more on a display and are totally satisfied with a $399 HTiB, some spend $20k, $30, $50k or more on the audio side and are happy with an RCA CRT console that was $399 15 years ago,....
So,... If "I" had a $1000 budget today for the audio side of a Home Theater,.... I'd go with:
EMP Tek HTP-351T for $689
Denon AVR-1908 for $298. I think you'd need a 1909 to get the Dolby True HD and dts HD so the Onkyo TX-SR606 for $348 may better fit your needs.
