Your questions very subjective.
My Opinion - if you want to watch television that's okay. If you want a true Theater in the Home/Larger than Life experience then get a projector and screen.
That 50in TV you are considering is not capable of a Theater experience - our 56in TV is not capable of a Theater experience. Our opinion, NO tv on the market today capable of delivering a Theater experience.
If I do the math right your room is about 18 1/2 ft. long.
If you did a simple shelf projector mount (as we did) your throw allowing room for PJ and cables would be approx. 17 ft and depending on the projector a zoom/throw flexibility you should be able to fill a 100 inch screen with a nice even larger image diagonal.
Then you can move the seating back a bit and achieve a good two rows of seating Theater configuration.
We love our tv for tv watching but when the lights go dim and the Theater sized screen lights up then Theater in the Home occurs!!
You've got what looks like a very good room for even both TV and Theater if you care to have both options.
goodluck
