Auto populate password for Shopping Cart Software.

On my website, [login to view URL], I need: 1. Change the word "Vendor" to "Seller" on the "Become a Vendor" button and on the Vendor signup page. (Image included) 2. To have the password field removed from the Seller Signup Page. (I'm going to need the password to auto populate.) (Image included) 3. When a new seller signs up, I need it to auto populate a random password and email it to them along with their user sign in. It should look something like but limited to this: Thank you for becoming a Seller on Hobnoben! Here is your login information below. User: xxxxx Pass: xxxxx (this is where the password should auto populate.) You can begin selling now by clicking the link below. Now go get 'em! [login to view URL] (Please link this url) Note: The Vendors information already auto populates in the back office. I Do Not want this to change. After each number is complete, it will be followed by a milestone. Remember - this is a shopping cart software, I need someone experienced please.
