I'll help with all that I can:
1. There are supposed to be 2 new shopping centers going in but with the economic condition those may be delayed at best. The shopping center that currently houses the WM SuperCenter has been redone. I don't know if there's a Clinique or anything like that, however. There is a "mall" but it can really scarcely be called that.
2. No for both in Russellville. There's probably a Sam's in Fort Smith though and definitely one in Little Rock.
3. Pretty sure there's still a Hobby Lobby and I'd imagine there are other sewing shops but not 100% sure.
4. Several hardware stores will carry your clamps and glue. Not sure about actual tools though. For wood, I'd make friends with a good old boy from up Dover way or something that like and have him give you a decent supply in exchange for a piece or two.

That'll get you set for oak and hickory and maybe a few other things but real exotic stuff will probably have to be ordered online.
5. No idea, can't help with that one.
