Essentials to an affordable HT!!

[nothing.sound]

There are so many threads discussing different aspects of a home theatre I thought it would be nice to condense everything down a bit. What are some things that people with a reasonable budget should have to enhance there home theatre. Add anything I have missed! This is mostly for the video portion as I am not really up to date in the sound world. Remember lets keep it at a reasonable cost which most people could afford.

-1080P HD t.v set / projector
-Blu Ray disc player
-Blu Ray Movies
-6500 kelvin light behind t.v
-power conditioner
-t.v. professionally calibrated
-hdmi cable

I'm sure there are alot more little gadgets or things you can do so please add anything you can. Also if some one can do a list for sound that would be awesome.

Even think of things like what if you had your t.v. on it's own circuit would that make a difference. Or seating distance and how high should the t.v be. Just anything you can think of.
