yes Mu is +2.61 and -5.1 kip-ft, but you have to make sure + sign represents inner or outer face of wall. It will depend upon the direction of local 3-3 axis.
Furthermore, you dont need to design (Mu) for peak/max values shown in status bar of ETABS/SAP/SAFE.
This should be enough for longhorns but to be a veteran you need to look at other things too. Read a good book about FEM. It will really be an eye opening and advantageous for you.
Read how to take design values from contours, what are stress concentrations, what Guass points and how meshing affects stress concentrations.
In short for a simple problem, yes, use M22 moments for vertical steel design and M11 for horizontal steel of a wall (if default orientation of local axis is used)
