Update attributes for all products?

Hello,

I just used easy populate to add around 50 items to my store.

All my items can be sold in different sizes, therefore I used the attribute manager to set up the Option Name and Option Value.

Since all the products should have the same price as well, I'd like to batch this process somehow, and add all the option names & values to each product.

Is there any way to do it, instead one by one?

Thanks !!!

Ok, I think I found one more problem.

When using Easy Populate, I'm uploading all the products to the English language, but the I have no products on the french language.
Is there anyway to solve this issue?

Thanks

One last thing - I can see on my front page the "New items" just with capital letters. is this normal? How can I change it?
When I'm looking in a specific category the names are ok.

Help will be really appreciated!
