I want to Super-Charge my Zen Store for Web 2.0 - Syndication, XML, Feeds, Networking

Hi
I want to make my Zen store "Web 2.0".

I am considering:

(these are by magn etic one)
Zen Cart RSS Export
Power SEO URLs for Zen Cart - Zen Cart
XML Sitemap for Zen Cart - Zen Cart module
Zen Cart RSS Aggregator
Zen Cart RSS Export
Zen Cart All-in-One Product Feeds
Amazon Data Feed

and/or

SitemapXML (open source)
Simple SEO URL (open source)

And any other recommendations!

Im looking for a solution where all the addons work together. I want to drive loads of traffic to my site and have news feeds, possibly a blog, integration into social networking etc etc

I am interested to hear what free and paid addons people are running and what success people have had with these and if they conflict with each other. How can i make use of so many available add-ons to drive traffic to my site? With the data feeds I am concerned that they should work with whatever SEO url solution i use.

I dont want to totally mess my store up so that I cant install future addons and patches without having a com-sci degree! My programming skills are limited

I hope this might turn into a useful thread, since there are so many threads on different subjects and add-ons but dont seem to be many with an overview of which we should use and how they go together.

What is an ideal set up?

My site is a flower delivery store I am also looking for a way to have extra customer information boxes in checkout (currently there is only one)
