well it can be a lot easier than you think, fortunately the seedling does all the heavy lifting and does the growing, you just have to try to provide the best environment as possible.
also fortunately those plants you listed are tough cookies =) those are all easy plants to grow in general, the paw paw is a bit more delicate than the rest, but they all
should be fairly easy and hardy.
i dont know what your set up is like but all of those vines would love to be in the ground and grown on a
trellis in a permanant place. you can grow them in pots for a while if you arent ready to decide where to put them, and the end of the growing season is near. but they will get a lot bigger and really take off once you put them in the ground around a trellis or something else they can climb, like a
fence.
the passionflower will probably die back to the ground over winter, and then pop back up next spring, hence its name "maypop" cause may is about when it pops back up from the
roots. the kiwi and muscadine will lose their leaves over the winter and then take off next spring again.
at this time of year its too hot for any sort of covering, they would be fine in pots uncovered. over winter you might have them in some kind of covering, but the plants you mentioned should all live without being protected in zone 8
once you choose a spot for them prepare the ground...i would suggest sheet mulching, though theres a variety of ways to go about preparing the spot where you will transplant them.
maybe someone else will come around with a how to simple guide, or perhaps you should get some
books. its a pretty big subject to get to know, but the way of just doing it and figuring it out as you go can work .
i'd like to inspire you to not be intimidated by it though, it is easier than one might think, the plants want to grow and just by paying attention to them you can usually figure out what they need.
