So here's my question. Is it ok to have multiple shallow grounding
rods versus one longer grounding rod? For example, what's the
difference between 2 four foot rods versus 1 eight foot rod?

Dan, you didn't mention the type of ground you're seeking (safety, RF
or lightining). If lightining, here's a good place to start.

Sorry, I should have been somewhat more specific. I'm looking to
create an RF ground.


A couple of ground rods is not going to make much of an RF ground.
Do you actually need an RF ground? Being you will be on the 2nd
floor, I bet you would be better off without one.
What will the antenna be?
You would be better off to use a "complete" antenna, and that way
you will not need an RF ground in the shack at all.
An RF ground should always be under an antenna the way I see
things.
Trying to rig up an RF ground on the ground floor, and then rigging a
wire from it, up to the 2nd floor, is a mistake, and will just act
like
part of the antenna.
Myself, I would not even bother.
Heck, I'm on the ground floor in this shack, and I don't use an RF
ground to the shack. Haven't in nearly 15 years...
