Change Error Messages

Hi,

I'm currently using ver 1.3.9h and template forest path.

I have an attribute within a product (size-colour) with option values of E/Oak S - XXXL & H/Green S - XXXL.

Currently I have two of the options set to display only as they are not available in stock so I would like to replace the Error message that a customer gets** 'Please correct the following:
On the Option for: Size - Colour You picked an Invalid Selection: E/Oak Large'** to, 'Sorry the item which you have selected is currently out of stock'

I would also be grateful if anybody can tell me how to switch off the message 'This product was added to our catalog on Thursday January 01, 1970.'

Thank you in advance for any help.

That was my first port of call but when I tried to search for the message string it came back that no files were found!!!
