Haha, well I suppose living somewher as remotley beautiful as Northern Scotland has to have it's downside!
No worries with the help. Though my knowledge is, and always will be, rather vague!... Even more so with KDE as I'm new to it too.
Do you auto-login at boot? I seem to remember from Gnome that using auto-login caused gnome-keyring to hassle for passwords, perhaps stopping would make all this go away! (Under Gnome your password opens the keyring upon login).
You could try stopping network manager from storing your wifi key in kwallet;
Click your wirelss icon, select 'manage connections' then 'other'
Change 'Store connection secrets' to 'In file (unencrypted)'
Still getting hassled?
Perhaps set a blank password for kwallet which will stop it from asking, this does mean anyone with physical access to your computer would have access to your stored passwords. (Firefox's password manager is seperate so I imagine safe)
The same would apply if you were remotely hacked, but then how likely is that!? …... By the sounds of it they'd probably get bored with your internet connection anyway!
alt+F2 , search and open kwallet manager, right click on kdewallet and select change password. Enter your login password and then confirm new blank password.
Though please do note, I'm not fully aware of the security issues of a blank password. I'm half expecting someone to wade in...
NOOOO! NEVER LEAVE YOUR WALLET OPEN!
Actually now I put it like that, I'm not sure about it either!
