SBIRIT has a huge grant going right now to push for integration into primary care.
The third link from ClinPsychEnthus is an awesome book (I own it) and if you arent already familiar with IPC it gives you a good framework from which to begin.
I got a CBT-I group manual emailed to me last week per my request, and I'd be happy to share it.
For primary care, I'd be more concerned with health behavior change than doing formal CBT-I (e.g. doing parts of CBT-I such as sleep hyiene).
As I've spent a few years in primary care, if anyone needs additional resources, I'm glad to share.
Most importantly, I hope you can win over the docs there-- that's the biggest challenge as BHC's move from co-located to integrated over time.
