Tee-Hee, Diane. One concession's worth another ~ fair trade

I don't believe I have come back on the computer before bed to talk about arses.
The depths,
isn't 
it!?!
You're right that our "ass"es get a lot more mileage than your "arse"s; however, even in the samples you gave, it's still consider more 'vulgar' speech than not. Nothing that most can't 'handle,' but still like a layer of dust on a person's locution. With much intensity, it can be like some caked dirt, or even mud, if it gets too heavy.
"Don't worry your silly ass about it" would be another variation on a theme. You're right-on with the others, and they
do get used a
lot here.
Hmmm.
'Arse' does have a bit of a jocular slant,
Yes, exactly. You got it ~ jocular and the connotation that goes with that.
Uhhh, yeah ~ "arse" end works for me
