This is a general answer with a military slant, without going into too much detail:
1. Fly the approach as per the plates and intercept the ILS (possibly call "localiser established" and "glide path descending" at the appropriate points) and await freq changes (unless plate specifies where to do so) and landing clearance. If no landing clearance then perform missed approach procedure on the freq indicated.
2. Probably maintain that heading to ILs intercept then as above.
