That's strange. This airplane, like the vast majority of turboprops, doesn't have a nose-up approach. Usually around 0ยบ.
Do you have the correct Vref according to your weight?
For the LOC, I'll need to try it out, but I believe you had to tune the ILS freq yourself and then select what type of nav you wanted the AP to follow (FMC, VOR, HDG or APP).
