I am using Google Sites, Google Checkout Gadget and Google Spreadsheet to sell downloadble files.

There is a ton of help material on Googles site I have read but I am confused  and hope someone can help me.

My questions are:
How to I link my customers purchases to a digitally delivered file via URL -Pessimestic?
In my spreadhseet I have an image link and I cannot figure out why the image will not display on my site?
If I use the Google Checkout Gadget can my customers purchase multiple items at a time?
I cannot get my layout to change on my Google site.  There is a box on the right behind my embedded excel spreadsheet I don't want there and I want my side bar to shift to the left so my spreadsheet will fit completely on the page.
