Publishing directions can be found in Help, just search on "publishing".
Optionally articles are available at
http://www.publishermvps.com/WebDesign/Version2003/tabid/33/Default.aspx
As far as web hosts, they are a dime a dozen, typically you should get
referrals from peers. My recommendation is available at
http://www.davidbartosik.com . As far as ecommerce, Pub has no support for
back-end programming and processes.
Those that choose to use Pub as a store entity (
http://www.publishermvps.com/WebDesign/tabid/29/Default.aspx ) do so using a
third party provider such as Paypal.
