What do I need to look for when selecting new RAM for my MacbookPro8,1?
I believe that 1333 MHz is the max that the computer can handle. You're looking for DDR3 memory at that clock speed. Brand doesn't particularly matter. I personally like G.Skill, Crucial, Mushkin. If you're on NewEgg and sort by rating it's usually a pretty good indication of how the memory does and often times people post their computer model in their review.
