Complex WordPress Development :S

i need to create a wordpress website that has the following features :-

– Ecommerce
– Affiliate Products
– Multi Language (2 languages – chinese and english with good human translated pages – not free translated auto pages)
– Free Membership (people become members after ordering a certain amount of products and then on will get discounted rates)
– Wholesale prices (wholesale customers can login to get wholesale prices)

Any ideas of the best way to do this?

My current thinking is to use these plugins

– Wishlist (for the membership)
– http://tribulant.com/plugins/view/10/wordpress-shopping-cart-plugin (as it says they do support affiliate products) – other wise i was looking at WP e-Commerce plugin ?
– WP Multi Lingual Plugin for the translations

(anyone know if these plugins will all integrate? or what is the best structure or other plugins to use?)

Any help is much appreciated

cheers

Sam
