#1 Would an average FBI technician even know how to scan server logs?

The FBI has, or certainly can have, software to analyze log data for patterns of interest. These would use data mining algorithms and social network representation, at a guess.

What they are looking for?

Calling patterns (who calls whom, when), social networks (who's indirectly linked to whom via which third parties) and changes in patterns ahead of operations (op tempo is reflected in increased call frequency, followed sometimes by going silent just before an op).

None of these require access to the body of the email, just the header info.

Do they have even an inkling of how long even with today's powerful processors to scan four gigabytes of simple text even with simple tools such as cat and grep?

At least some of the software they use - or could use - is significantly more sophisticated than cat and grep. Many machine learning / data mining algorithms execute very fast after the more time consuming step of training them.
