A blurry image can't really be fixed.
Sharpening in Photoshop and other programs is actually a contrast enhancer that works on edges where there already is contrast.
When there are no sharp edges, there can be no effective and natural looking sharpening.
You can try aggressive settings, but they will look unnatural and usually make the photo look worse.
I think you probably were into the range of longer shutter times where handholding a camera becomes difficult. (There's no exif data embedded in the jpg so I can't read your settings, so I'm guessing.)
Anything slower than 1/60th of a second is dangerous for many people--on your LCD or viewfinder it will just say 60--and remember that 30 is slower/longer than 60 and even harder to keep steady.
Use a tripod when light levels are low and you're not using a flash.
Or use a higher ISO, but you have to be aware of how much digital noise your particular camera will add at each ISO setting. Some people don't mind the grainy look, others hate it.
Or use some brighter lights in the room next time.
I have a handful of cheap desklamps and clamp-lights from the thrift store, and use 100w "natural" bulbs in them.
As for the orange, what happened was that you didn't set your white balance to incandescent (or tungsten)--the screen icon is a light bulb.
Using auto-white balance sometimes works, but isn't dependable.
To tell the truth, Fiona, I like this photo as it is.
The blur isn't bad, and even resembles certain Photoshop filter effects that someone might use on portraits like this.
The black and white conversion you did looks like a basic desaturation, so a little more contrast would add some punch to it.
Keep trying, and you'll get there.
Here's a quick edit i did using IrfanView, a neat little free program that I use when I don't want to open Photoshop 7.0 which is a resource-hog on my old computer.
I added some contrast, reduced the size for posting and sharpened it twice.
Not too bad, really.
But nailing all of the details when shooting makes later adjustments more subtle and natural looking.
Hope this helps.
If you post some color versions, or better yet link to a place where we can see the original files straight from the camera I'm sure some of us would be happy to edit them for you and tell you what was done.
