Vengeance 16gbkit vs redline or blackline 8gbkit

no particular difference between the two unless you are doing a ridiculous overclock as both will run at 1600 stock, and both can likely be OC'd past the point they are rated for. If doing an extreme OC then perhaps the Muschkin would be better as the timings are lower (generally, but not necessarily, meaning that it is a higher quality product), but really there are so many variables that there is no way to know for sure unless you were to purchase both and try them.

I am curious as to how you got to 2 very different Rams, in completely different price brackets. The Corsair is super high density ram, and a bit slower, meant more for productivity work where you need 32+GB of ram in the system. The Mushkin ram is made a little more for OCing with slightly tighter timings, and a higher binning (1866 instead of 1600). Remember that Corsair and gSkill make 1866 ram as well.
As of now I would stick with 4GB sticks of ram, and get 4 of them. Remember that Win7 home will only support 16GB of memory, and you have 4 slots on that mobo, so a 4x4GB config would best suit your needs. Assuming that $130 is your budget (what the Corsair costs) I would go with something more like this:

or the sister version in red

Or if you do not need 16GB then go for a 2 pack instead of the 4 pack:
