Form shortcodes + payment form redirect

Greetings all... I would like to ask you a few things I need some help with.

1. Can anyone provide me with a complete list of form shortcodes for the Membership plugin? I'd greatly appreciate it! (you know the shortcodes you include in pages and posts in order to render a specific component)

2. How can I redirect any button click I want to the payment form?

3. Is the language file EN already connected, or do I have to enable localization somewhere (it be good to know b4 I start with translation)...

Appreciate any input you can give me.... Thanx!
