This shouldn't be so complicated.
Watts / Volts = Amps

That's what I did, I came up with 4.8A. Just wasn't sure if it was like wire where you calculate your total load to be around 80% of the wire capacity or if it was different.

might be another dumb question but I'd rather ask and look like an idiot than screw something up and look like a bigger idiot. I've got one switch powering 4 separate led strips around the perimeter of the truck (like a ground effects kit), each strip calculated at 2.4A or 9.6A total. My question is, do I fuse the line before it splits out to the 4 strips for the total load or do I fuse each strip individually after it branches off.

Put the fuse on the main line, not the branched off parts. You want the fuse to will act like a switch if it blows, killing the whole circuit.
