Shipping not calculating; newsletter question

[ristretto6]

Okay, two more quick questions before I leave for the day--

 

1) I've entered all my shipping rates (mine is tiered by weight) and am testing it out by putting items in my cart in the storefront.  It adds up the item totals correctly, but doesn't register that there are any shipping costs, even though I inputted that each item weighs 0.5 lbs when I was entering them as new products.  Shouldn't it calculate that this would be 1 lb. total, and assign it the shipping rate for my 0-1 lb. range?

 

2) I was trying out the login with my own information, and am wondering where I can edit the required fields?  For example, I don't want it to ask the gender of the customer, and I don't want to have the checkbox that asks if they want information from our partners.  I do want to keep the checkbox that asks to sign up for the newsletter, but I never configured this option--I do in fact have a newsletter they could sign up for; where can I tell Prestashop the information about it?  And what is it doing right now, by default, when the customer checks that box?

 

Thanks again for everyone's help

Answer for 2. question:

You can make changes in registration formular in file authentication.tpl (themes/prestashop).

for example:
if you delete this:

   <input type="checkbox"name="optin" id="optin" value="1" {if isset($smarty.post.optin) AND $smarty.post.optin == 1} checked="checked"{/if} />
{l s='Receive special offers from our partners'}

There will be no more Checkbox - special offers from partners
