first e-shop

Hi,

I need to create an e-shop in PHP.
this is for me the first time that i need to do that and i think the way how
to approach such topic is different that creating a simple corporate web
site.

Here are the standard features that i need to implement:
- home page including latest "article/news", offers, discounts, material
tests

e-shop should:
- allow users to search good by selecting a category (and/or sub category)
or by specifying parameters in search tool
- allow users to browse goods
- catalog of good should be browsable offering a short description of the
good, name of good, picture, price and link to more detailed information
- allow basket usage for ordering goods.
- allow payment by several using different methods (credit cards, paypal,
and so on)

Administrative part of the web site should also:
- allow archivings of old article/news, and material/good tests
- allow composing of articles, tests, and so on including pictures page
setup.
- allow management of goods and catalog.

as you can see something really standard however, i would like to do it
well from the beginning, so i would like to know if some example or tutorial
(even if partial) exist on internet
and for sure,, you are experienced in such topics, so to what should i pay
attention ?

thanks a lot,
