Can anyone tell me whether I'll be able to simply swap out the existing memory with this new memory?

yes you can.

Also, should I/could I upgrade my OS before/after installing new RAM?

 

Thanks!

not necessary unless you want to.

Yes, it looks like that memory should work fine with your computer.

Here is the link showing what your computer supports:

5,1 supports 8gb without the firmware update.  That article is for the non aluminum 4,1 models.

Oops, thanks for catching that.
