Profi template: Question on WPML and content locking


I am building a new webpage with the Profi-Template.
Therefore two questions came up where I need help.

First one: The webpage will use WPML. What is the best way to go ahead: Implementing the theme, then enabling WPML - or the other way round? I guess it will be implementing the theme, so WPML “uses” the content.

Second question: I want to “lock” premium content on the webpage. Is the Opt-In Content Locker from Codecanyon the best implementation for the Profi theme (I guess, as it is part of the enviro-community, but want to be sure before going ahead).

Thanks a lot for your hints & help, I appreciate this.
