Hi Alexban,
Yeah, the limits you want are 2.5 to 3.25 degrees, with 30 and 40 flaps, and both engines operating.
Also, the autoland system is not certified for overweight landings, an approach on autoland is OK, but must disconnect and land manually.
I have these figures in my AFM. (B737-6/-7/-8/-900 airplanes.
Cheers
