the ultimate set up

Now I am actually an analogue die hard, having never really invested in CD's, but time moves on, and I want to be able to use my computer to store music on the hard drive, and then via my amplifier - I am tempted to go the room correction route as well.

now - how do I go about it namely?

1. how powerful must my PC be?
2. what ripping sotware should I use?
3. what type of hard drive do I need - would a flash memory get rid of jitter?
4. when outputting should I use a soundcard, or an outboard dac and if so which one?
5. should i invest in a streamer so that I can put my pc in another room and reduce noise further - again which one - squeezebox duet - the modwright modified one, or the new one from chord or resolution audio
6. what room correction software would you recommend?

please note I am after excellent sound quality forst and foremost - I have a pretty good vinyl based system that's worth about £7000 for the turntable/arm/cartridge alone

I would be very grateful with help in this department.
