I would not use those rollers, I have seen the yellow ones like that and the foam is not as smooth as the ultra smooth foam rollers you should be using.
Do you have a store that sells just paint in your area? They would most likely have the mineral spirits (sometimes called "Paint Thinner (100% Mineral Spirits)", and the dense foam rollers.
Here is a pic of the rollers I've used, next to mineral spirits disguised as "Paint Thinner". These rollers are from Home Depot but im pretty sure lowes has the same ones. Local sherwin williams has a similar kind (they have ALL been white) but were more $.
