Arkansas CCW Questions

I'm considering moving to Arkansas. However, local gun laws are a concern for me. I'm from Arizona, which has been voted the gun-friendliest state in the Union.

1. Is Arkansas a SHALL-ISSUE or a MAY-ISSUE state?
2. What do the laws say about carrying into businesses which sell alcohol?
3. Does Arkansas allow carry into government buildings - even at the town level?
4. Are there restrictions on caliber or ammunition type or magazine capacity?
5. Are there restrictions on carrying two guns at once?
6. Is open-carry allowed?
7. Is printing considered brandishing?
8. Is there a stand-your-ground and/or castle doctrine?

Are there other things I need to know?
Thanks in advance!

Here's the obligatory "go check http://www.handgunlaw.us/states/arkansas.pdf" post. lol

Looks like it's "shall issue" but "must inform," and the no gun signs have the force of law... Coming from AZ, ouch.
