the quickest (and easiest) way to edit templates is to use the webmaster mode in the admin section... or you can edit the templates directly.

you will find the footer in the following file:
skin1/bottom.tpl

comment out or remove the following code:
{include file="main/prnotice.tpl"}
{include file="copyright.tpl"}

or alternatively you directly edit those tempates.
skin1/main/prnotice.tpl
skin1/copyright.tpl

be careful if you got to edit the featured section as it calls the 'dialog.tpl' template that is used every where you see a box on the screen.

to remove the 'send to a friend' you will need to edit the following file:
skin1/customer/main/product.tpl
and comment out/remove the following code:
{include file="customer/main/send_to_friend.tpl" }
