Widget Trouble

[Bluzin1]

I installed several apps.
To install battery I had to go to install widget..
I tried to move it and got 3 app icons on my screen.
I uninstalled app and now I have 3 "Problem Loading Widget" in gray windows.

Also -- somehow I duplicated the market icon.
How do I delete the 2nd without causing issues ??

Thanks,

Bluzzzz.
