Need to improve my system any input would be great (Possible 56k warning)

Right as you can see this is a long post so sorry up front!!

Here is a picture of the side of my case, I have a dual case setup with two bolted side by side.



This is one of the first pics i took when system was made and here is the flow in my amazing paint pic



First thing is the big S shape tubing going from the res to the pump I want to get rid of this but want a good bleed fill point. With regards to bleeding the air out I have to assemble the water cooling in the case so can't move the rad around to make sure all the air is out. I know it has a bleed hole but i am never sure if all the air is out due to the fact that I cannot give the rad a good all shake to make sure.

Next question is the flow rate I want to upgrade my pump and have been looking at these three pumps they are:-

With this Iwaki whats the difference between American and Japan version?

and finally a cheaper pump but well used

What do you think of my options I am not to bothered with price as I can save up but is the Iwaki the best one?

Also the reason I would like the Silverprop GPU block is that the top is 100% brass not Anodized ALU as I never trust Anodize again after the inside of the maze 4 block has worn pretty thin.

Any help on these subjects would be great go easy this is my first post
