Htib
I assume when you say "kit", you mean a HTIB (home theater in a box). There is many to choose from. Myself, I'd go with a Denon, Panasonic or Yamaha. (notice Bose does not make my list).
Here's a site with examples:

In some cases the only connection you will need is the HDMI. If this is the perferred method of watching TV, than the audio connection part of the HDMI is not really needed since you won't be using the speakers on the Sammy.
The choices will come down to either a 5.1 system or a 7.1 system.
