If this scene offended you (Trisha and Hohenheim, right?), then you may have a minor problem with a few things later on in the manga. But I assume this kind of essentially non-sexual nudity isn't a big deal, in which case there isn't much that will bother you. Some of the violence is a bit more brutal than seen in the first three volumes, but not much. At one point later in the plot it becomes important to see Riza Hawkeye's back, which happens in a shower scene, but again this is brief and not intended as fanservice.
As far as quality goes, I'd encourage you to get the manga. It is superior to the anime, in my opinion, and develops the latter part in a more balanced way.
