The Canon plugin works well with Log and Transfer. It's the fastest way to bring the H264 format of the 7D into FCP as directly as ProRes. It also has the added and extremely useful benefit of translating the camera's time of day recording into a timecode track, its the only ingest system for this format that currently does this.
The audio on the 7D is inadequate for a feature. PluralEyes works well but I'd still use a slate for better organisation.
Your big problem will be if the location crew doesn't follow a workflow that is organised.
The most reliable way to bring the files from the CF card to a drive is to use Disk Utility to record a New Image. This should then duplicate this to another drive for security. You and they need to get together and decide on a suitable workflow these files and associated audio tracks, renaming and putting them in folders so that you aren't left with a massive task of trying find what goes what before you start to edit.
