Several minor aesthetic issues that I need help on

Since my "login page" issue was solved just by doing a new install of the site ... I extracted my remaining issues from that thread.

Now, if someone can help me get the login page to look nice in both FireFox and IE:

1. All sections of the form(s) to be left aligned. DONE

2. All input fields to be left aligned. DONE

3. In the newsletter section, have the appropriate text next to the appropriate checkbox/radio button

4. Have a left margin between the left column and the login page.
   In Firefox it's up against that left margin. Any time I change widths of <div>s or such, it affects the breadcrumb trail's width. Go figure.

5. Have all the red * line up appropriately with their associated boxes DONE

Also - the left column search box is messed up, especially in Firefox. It was like that from the fresh install - no modifications. I even copy/pasted the code again from "virgin" zencart files and from another site I installed.

Lastly. I was able to do this just fine on another site. But now I can't get the add to cart to layout horizontally:
Quantity: [box] [add to cart button] I even copy/pasted code from the site that it is working on.

W3's validator says my code is clean.

Thanks in advance for any help you can provide.
