I am unable to run my signed, release keystore in Eclipse:
I get the error:
Keystore was tampered with, or password was incorrect

The easiest way is to create a keystore is from inside eclipse itself as part of the export process. When excporting your app click the option to generate a new keystore. Fill out the appropriate information and Eclipse will generate a new, valid keystore for you.
And always backup your keystores. I have a usb drive that has a copy of all of my keystores.
