To speak to the second of naming things, I'm a big fan of content addressable everything. Addressing all content by hash_function(<the content>) has major advantages. This may require another naming layer to give human recognizable names to hashes, but I think this still goes a long way towards making things better.

It also requires (different) attention to versioning. That is, if you have arbitrary names, you can change the referent of the name to a new version, but you can't do that with a hash. You can't use just-a-hash in any case where you might want to upgrade/substitute the part but not the whole.

Conversely, er, contrapositively, if you need referents to not change ever, hashes are great.
