Bit of advice needed on complete new midrange system

Hi all,as the title says I am looking for the whole lot.I have done quite a lot of reading of forums,reviews and news etc, and I have to be honest my brain feels like its leaking out of my ears with whats available and all the options of what does what.

I currently have a mix of mainly old and tired gear which,if the plan is ok will all be replaced.I am not an audiophile I just want a better and more modern setup .The current hi-fi was just these 3 items.The TV and err "surround sound" shall not be mentioned!

Denon ADV - 700 amp

Denon DCD - 635 cd

B&W   DM 601 S2  speakers

The new system Will be used obviously for movies through the blu-ray,virgin media Tivo box and streaming stuff from the pc/net like Photo's,music videos and maybe movies.This is one area where im not sure what services from the Tivo will overlap with the blu-ray and if it will do those things i want...

The amp looks good .It has airplay for the itunes library and that two way split which is nice as i can use the old B&W speakers in the study.Which is directly behind where the Kit will be sat.So just a hole through the wall for cables.

This is what i was thinking of replacing it with,in the order in which it will be bought/installed so i make sure one thing at a time works.I do know that the amp and the blu-ray are not released yet in the UK.There is no massive rush for it.

Samsung UE40ES5500 TV- Assuming with everything else in the shopping list i wont need the dongle and i dont want/need 3D

Tivo- with the virgin package i get 60 meg broadband so streaming should be no problem,i hope

NSZ-GP9 blu-ray

Yamaha RX-V573 amp + 5.1 speakers.Not 100% sure about the speakers.Looks like i may go a generation or two back and get an outdated model.Seem to get a good set of speakers for a lot less.

Any Connectivity problems,advice,opinions,words of wisdom or cries of noob are greatly appreciated.

Cheers, Tony
