I know about desktops and such, but Im still learning laptops. So does a sata 3.0 work if a sata 1.5 does? Or does it have a different hookup?

They use the same connector, and, generally, most of them are interchangeable. Some drives act funny when on the wrong bus...but I've only found a few that do so.
It should work. The connector is physically the same, and in 99% of cases, it is perfectly backwards compatible.
Get the WD Black (I have the Blue), and it'll be fine the controller handle the aut detect (no jumper needed). The only thing I've even heard issues with is NCQ is a drive to drive issue, but that could be controller to controller quality really.
