What's the name of that country between The Shaar and Halruaa?

Chungusland. :P

Why hasn't the Cult of Shar sued the Shaar for copyright infringement?

Because the Church of Shar is too busy using their lawyers to grief the Mystrans and the Selunites with frivolous lawsuits.

That name is clearly written to confuse an idiot at a glance.

Not really. It's just that the Shaarans are not very imaginative people when it comes to names. ;)
