Need Help in the Flats....

I will be in the Charleston area; 5/11 -5/14. I have a few questions about what is happening in the marsh.

What bait is in the creeks, far up the rivers?
Have the schools of Reds broken up?
Is there any action in the creeks off the inlets?
On my last trip two weeks ago I noticed very small shimp up the creeks, does anything other than Mullet get attracked to this bait?
During the visit I had wind problems so the fly rod didn’t get much use, but if I can modivate myself I plan to catch the early high tide on my last day. Will I find and Reds in the grass?

Any help is appreciated.

Also, I have a 2001, Mako Inshore 2000 w/150hp for sale if there is any interest.
