With what you are describing and the cheap cost of RAM I would say go with 16GB of RAM.
Go with a speed that will work with whatever overclock you plan on your CPU. After that, get the fastest RAM for the "sweet spot". IE: don't drop double the price on RAM that is 33mhz faster and will give you 0.000133% speed increase.
I don't believe brand matters too much. I have never had compatibility problems with G.Skill so I keep buying them. Definitely make sure you get lifetime warranty.
If you are going Sandybridge then get 1.5 volt or less. In fact, sometimes the 1.25 or 1.35 volt RAM isn't that much more and it's better for overclocking or running low voltage. Probably be best to do 1.5v that way you can have maximum resale or portability between platforms.

and brands matter

too much ram
On black friday I "uber price matched" at memory express some $56 2x4gb ripjaw kit with new eggs $30 black friday price and they beat it by 25% of the difference and gave me each 8gb kit for $26ea.
If you can get 8gb of 1600mhz memory in the $25-35 then go for 16.
