Mealybugs (I think) on my Jade

I was about to repot my Jade plant a couple of days ago when I noticed that there were little black insects, tiny, really, clustering amongst themselves in the plant. I googled it but couldn't find any information on black bugs. I've been meaning to call the nursery where I got them, but have been busy for the past couple days and when I checked it again today I saw that the bugs (presumably the same ones) have turned white! Googling that showed mealybugs-but there's lots of conflicting advice. Does anyone have any ideas on how to get rid of these little jerks? I like my Jade :)
