Any recommendations or advice for ABOLC?

You're a prior NCO so you know what it is like to lead from the front. Don't hesitate to take leadership opportunities head on. Not only will you look good because of it, your peers will look up to you for it and it helps you to become a more aggressive leader. Always accept the most difficult and uncomfortable tasks. And help out the 2LTs who are new to the Army. They'll be your friend for life.
As a prior NCO this is the approach I took in OCS and in FABOLC and I did pretty well. Good luck and congrats!

If any old kook tells you any combat arms BOLC is a gentle men's course, don't believe it....be prepared to put in a lot of work and full days and sometimes weekends!

It has been almost a decade since I attended, so my info is dated. I'm sure the POI has changed a bit. That being said. I recall having a substantial number of 1900 or later returns to the house after spending all day in simulators or classrooms. I also remember being downright exhausted during the field problems and the CULEX.

Study hard and apply what you learn to the problems they give you. Also, be ready to take charge and lead at 100 MPH. It is BOLC, so they want to see you lead and they know it wont be perfect. Make your recoverable mistakes there. Good Luck!
