Hello — in the settings for the behavior of 8way, there is a Rotate setting set to no, actually I think its called 360.
For the second part I think you mean you want the guy to look as if he is walking to the right when you move him right. what you can do whichs works well is create 4 different animations in the Sprite, North, East, South, West. In each of those have 4 or so different frames that show movement, then in your Events, you have a condition that says if Right Arrow pressed change to East animation, when Up is pressed, change to north etc... works pretty well and is simple.
