Page 1 of General questions re DVD/receiver prior to purchase

My, oh my, its all changed since the 70`s when I`d wander down Tottenham Court Rd, pop into Laskys, and knew whats what!

Its time for me to get up to date, but I`m confused. I`ve done my damndest to read up, I`ve wandered into Richer Sounds (& wandered straight out again!)

I want to buy 3 things, starting with a digital 28" TV. As the last Sony has lasted 22 years, I`ve talked myself into a Sony KD28DX40. It has virtual Dolby + Freeview digital tv & radio. Mind you, trying to puzzle out how this differs from the KD28DX40 has made me grey even more, so...
Question 1) anyone know the difference?.

I`m no sound purist so I want a DVD mainly to play MP3`s. I thought I`d go for a Sony DVPNS305 (£120 at Richer Sounds + £20 for multi regional). I don`t think I`m too fussed about USA dvd`s, but ...
Question 2) is there a `hack` (its got to be easy) for the Region 2 one?

If you`re not fed up with me yet...

Being used to Quadrasound in the 70`s, Virtual Dolby Surround sound is ok for me, I don`t want 5+ speakers. But, I`d lke to use my 2 existing external speakers when listening to music. And I`d like to get radio.
Question 3) Am I right in thinking I need a receiver (aka home cinema?) to do this?

Question 4) Could I finally connect up the Video I already have, thereby ending up with a system comprising of:- a digtal surround sound tv, 2 external speakers (optional), a dvd and a video?

Please don`t make me get my walking stick out again for another wander into Cheaper Sounds. Thanks for any help.
