Maintain Weight, Build Muscle, Lower Body Fat %

So, my long term plan to get to my stable (if possible) 75kg, is to first get to 80kg, and then try to maintain a stable weight at 80kg for a bit (182cm tall).



Now while maintaining 80kg I will want to be lowering my body fat %, leaning my body out, and building lean body mass.



Am I correct that to do this (on a basic level) I need to eat enough calories to maintain weight, and just do a lot of weight/resistance training?



Eating enough to maintain weight, will allow me to build muscle and reduce fat? Or is there something more complex to it?
