Valve cover! Yes! as it does tend to leak, fouling the plugs and coil packs, leading to rough running!
Brakes, if they are original yes! 10 years is a lot to expect out of a set of shoes!
Hoses, if they are also original them yes! The hoses crack from the inside out, you may not see any cracking on the outside but that dosn't mean they are not about to burst!
The other stuff is just general maintance, if you were keeping the Kia for a while then go for it, if she's running rough and sluggish then sure, but if you are running fine and only plan on keeping her for a short time them maybe not a hot idea!
