USPS error, templates, etc.. Help, I'm going bald!

I would love some clarification on a few things...

1. Every time I try to use the ecart wizard, I get alert messages stating that I am trying to change a part of the document that is marked as uneditable, and that the page will revert to it's original state the next time the template is applied. The only way I was able to get around this was to detatch the documents from the template. Will that mess them up later?

2. Now that I have finally enabled the extension_curl.dll in php, I am finally able to get to the shipping_failure.php page. Unfortunately, I get this error......"Notice: Undefined index: BlueSkyCart_USPS_ErrorDescription in C:\webserver\apache2\htdocs\ddc\shipping_failure.php on line 87" Any idea what's causing it?

3. When completing the checkout wizard and it asks for package weight (in lbs) should I enter 1, for one pound. or should I enter 1.00?

4. Should I be expecting any problems using USPS quotes with PayPal standard?

Thanks in advance for any help/advice in these matters. I've been at this for a few months now and my family misses their dad.
