Your latest four are far sharper - they are in focus and there is little or no hint of camera or subject motion. If you hadn't had a lot of noise, I think you'd find that these are pretty sharp.
I think part of your problem with noise and the very "bright" images is that you've got the meter set in spot mode. Combined with the fact that you're aiming at... black shirts (!) you're getting the black metered to be medium grey. This is the big reason why you've got such bright images, and since you're in effect slowing everything down by two stops, I'd say that this is the main reason that you've got a lot of noise, too. The noise in turn is making it really hard to do sharpening - the sharpening code is probably trying to sharpen the noise!
What ISO were these shot at?
