Component Advice Please
 

This will be my first custom loop. I have been researching, reviewing and learning tons. Now Here is what I have in terms of hardware and what I would like to accomplish

Case: Lian Li PC80 (I would like to place a triple rad in the front of the case like the one in the picture)
CPU: 2600k (would like to overclock to 4.8ghz)
Motherboard: Asus Maximus V Formula (not sure if this is even worh adding into the loop due to inlet size?)
GPU: (will be going with a GTX 680 which I might add to the loop down the road if needed)

Basically what I would like help with is the following:

My main focus is to have my 2600k @ 4.8ghz with a decent temperature. My questions are:

1: Due to space and configuration in my case I feel a tube resevoir (250 -60mm) would be best. Bitspower Water Tank Z-Multi 250 - 60mm Tube Reservoir - Clear or is there something else you would recommend? All parts will be purchased for Dazmode.
2: I am leaning towards the D5 pump. Is this a good choice or should I consider a DDC pump?
3: I would also like to use compression fittings, which brand is recommended and reliable?
4: Which brand tubing is recommended and reliable?
5: What's your favourite CPU Block?
6: Would I be better off to get the Raystorm Custom and use a Tube Resevoir instead of the one supplied or the EK Complete Watercooling kit H3O Supremacy 360 HFX?

Sorry for so many questions but it's been a learning huge learning experience and I value the opions here to make my final decision. (pics are not my computer they are from the internet, but of the same case I will be using)
