Try Gleim for an online course.
When in Dallas, make sure to find an eatery called 'Bone Daddies'...
If you are looking for a hotel with a free shuttle to FSI or CAE try the Embassy Suites in Grapevine. Make sure to ask for a CAE rate.
The other question I have is about the 3rd pilot that some cargo airlines use, so can some useful chap or chapess, confirm that if you work as a 3rd pilot, there is no requirement for a type rating ??
If you are a required crew member you will need a type rating. You need to clarify exactly what position you will be filling to get a more useful answer here. It all sounds a bit vague. If you do a type rating (under FAA, not an SIC ride) it will be combined with your ATP check ride.
Remember, jets generally don't like upship takeoffs. Don't try a weigh-off either in flight!
