I'd say all these suggestions are fine.
Now, are you trying to REPLACE hp numbers with descriptions for your players or just adding some description?
There's a huge diff, and I would avoid keeping the hp numbers away from your players. Its a lot more bookkeeping for you, and when you get into the clerics healing you back up and whatnot becomes a big pain. I once thought of doing that, but it ended up badly. No matter how you describe the damage to your players, he's going to be mad finding out he only had one hp left and didn't know it.
