Hello, Meredith....crikey, you've got a lot going on there.
These maggots in your radish are the same as those that attack brassicas and other root vegetables, though I've never had problems with them attacking beetroot.
Carrots do have maggots, but these are the grubs of the carrot fly and you need to be really vigilant to avoid these little blighters.
Radish with lots of leaves and no radish - most probably as a result of the seed being sown too thickly or they have not been thinned out sufficiently. Those in your pic with damage to the outer skin, is slug or snail damage.
Please don't be disheartened, these are all run of the mill problems that once you're aware of you'll take in your stride.
