I've noticed these guys in the garden for years but never bothered to find out what they are. They are bright red, move with great speed, have a single body, and 8 legs.

Mite

Seems it's actually a whirligig mite which is supposed to be a predatory insect that eats mites and aphids, and possibly scale insects.

What role do they have in pest management in a home garden? Should I move them to aphid or pysllid infested plants?

I found them roaming amongst the carrots and what's left of the potatoe leaves.

Whirligig mites will eat whatever is small enough for them to catch and pierce with their mouthparts, when they suck out the contents of the body of whatever it is they've caught, usually aphids and so on. They are a reasonably useful predator for small insects and shouldn't be discouraged or killed, but I wouldn't worry about moving them where you want them - a hungry insect (or in this case, mite) will roam far and wide looking for food, and if you put them where you want them, they will make their own choice about where they want to be anyway - it'll be wherever the pickings are easy and rich enough for them to stay for a while (much like any other living thing, including us).
