Skeletons with armor is not a bug as of 1.4.1 update, they spawn commonly with some form of armor.
But when they pick up swords and shoot arrows out of them XD!!! I think thats a little bug.
I experienced something very similar to this in the 1.4.2 pre-update.
However when I struck them with a weakness potion I wasn't able to hit the mobs at all until the potion effect wore off.
I think this is more than a "minor" problem though.

I have experienced this issue too.
I can confirm this, It happens to me all the time.
The only way to get rid of the flame is by placing a block on top of it.
Its basically a ghost flame (you can't get injured from it)

Does changing the direction you placed it in change the outcome of the "bug".
This may be how it should work.
I experienced the same issue.
I had named my dragon egg but the name reset.
Are you sure its not all the rain particles causing the lag?
I wouldn't consider this a minor problem really though, I think its something that needs fixed before the release.
I just looked, it could be that they are connected in a way as far as bugs go.
fix one and you would fix the other I'm sure
maybe disable the script for overworld skeletons to pick up weapons?
that way it erases the bug until you guys have more time to work on it?

I just tried this also, and I experienced the same results.
Didn't try slimes, the only mob I haven't had problems with is the skeleton.
Regardless, both are unresolved
