So you have your power and wind drift under control, it's all down to small corrections.
Some say you shouldn't even touch the yoke. Gentle (and I mean gentle) pressure on the rudder pedals for localiser, and use of trim wheel for glideslope. Some might not like that and will have their own tips and tricks. What does your instructor say?
If you are just starting then no need to be embarrased. It's not going to be easy, practice makes perfect.
