Well there's plenty of info on here about what is needed for TN-1. The only thing you need from the employer is a really detailed job offer letter saying how long they want you for (3 years max.), what the job is, why you qualify for it, what qualifications are needed for it, what NAFTA category it fits into, etc.
You can get it by applying for AOS using an I-129 but it's simpler to go to the border and it can often be cheaper as well as TN-1 costs $50 but I-129 costs $320. It's certainly a lot faster, plus you're there to answer their questions so that also can help.
