Here's some info from my Simcom E90 book.

Initial Maneuvering / Level: 800# - 160 kias
Descending: 300# - 160 kias
FAF Inbound (precision): 500# - 120 kias
FAF Inbound (nonprecision): 300# - 120 kias
Level at MDA: 800# - 120 kias
Visual Final: 500# - 100 kias
Missed appr.: 1200# - 120 kias


These were guidlines for the sim, but they should prove pretty accurate in the aircraft. Hope this helps and good luck!
