recommended Forum and eCommerce Software

[Wired4Film]

Hi, I've scoured the web and gotten some ideas for (FREE) Forum and eCommerce software, but I wanted to know if there's recommended software and/or plugins that integrate seamlessly with these awesome Revolution2 themes...specifically the Magazine:Church theme I'm using here:

Blogging Software:
I'm not a programmer, but can figure out quite a bit with good documentation, so the more intuitive the system, the better.
- Simple:Press - Anticipating a new version 4 upgrade, this might be the simplest forum to add, but how long til the new version comes out will be the question there
- Using Bluehost.com as my webhost, I have some good "native" apps I could easily add to the site, but "easily" to the Church theme?
a. BbPress
b. PhpPress

eCommerce Software
For posting site SWAG (t-shirts, etc), Amazon.com product clickthroughs, books, etc
- WP e-commerce Plugin seems to be one option
- WP-Amazon plugin

Again, anything's possible, but I'm looking for seamless integration with my beloved Church theme.

thanks in advance................../d
