The general guide for rads is one 120mm rad for every component then plus one. From what I see in your links you have only three rad "space". I would recommend at least 6 since its all crazy high end and it accounts for any overclock you do.
You don't need to spend that much on a pump/bay combo. If you want the redundancy of a second pump I'm sure you could find something else. No one needs two pumps unless you want to do an external rad and have the tubing go in the next room to be quite.
On a side note I'm happy to see your an evo fan. So am I, I just don't have one yet.
