OK, if it is a sim check they will probably vector you for a 30 degree intercept rather than put you on the ILS. Configure to F5 and use the FPV while you are in level flight well before the intercept, this will give you the datum pitch and power. Anticipate the LOC and make smooth inputs, do not chase it, as you see it coming from say the left, a normal rate turn will get you established no problems. Once on the LOC take gear down, flap 15, ignore the normal rationale of waiting for GS, this will reduce your workload and, as mentioned, you will need about 56/58 N1.
At GS Capture take flap 30 and accept the small speed excursions, but not less than MCP Speed (-5/+10kts limits), do not chase performance.
Once established on the GS, make very small inputs, the a/c is naturally stable, it is always PIO that mess it up.
Make small thrust changes to avoid the pitch/power couple displacing the GS.
At the bottom of the GS, no changes more than 2/3 degrees in roll and 1 degree in pitch should be needed, use the sky pointer and the track line. If you nail the track line all you have to worry about is pitch and speed.
A good technique is to imagine how you would talk someone through the ILS and then do it yourself. Good luck.
