Yes the Noctua heatsinks normally come with a variety of attachments for the various CPU configurations, so should be fine

, dependant on when this build is going to be built, look into Intel Haswell CPU's

, rumours are that by March it'll hit the shelves.
With the HDD as K4on says, you can save money there... As you have an SSD, then there is no real point in having a fast HDD as well, just put the OS and important quicklaunch apps on the SSD, all your movies and music will stream fine from a normal 6GB/s HDD (such as WD Caviar black)
16GB of ram is a bit excessive... Never used above 5GB on my system (tops out at 8,), and this includes some 3D modelling and highly space inefficient (but very speed efficient) coding.
