Where can I find answers to basic questions like these:

1. When a customer places an order how am I notified?

2. What is the function of the MySQL database? What get stored in it? Does it have to be on a SSL server?

If I wish to use Paypal for processing my payments do I need SSL at all?

Can I determine the shipping charges by the total weight of the items in the shopping cart (plus packaging) and the zip code (for Priority Mail)?

Can I have items which, if they are included in the order, force the order to be shipped UPS rather than Priority Mail?

I expect that such basic answers can be found somewhere but I don't know where to look.

THANK YOU.
