Just enable HLSL in mame.ini. When you run a game you can tweak the settings using MAME's OSD and see the effect immediately. I'm not sure if there's a way to get it to actually save the settings while editing, I wrote them down while I was messing around and then filled them in in mame.ini later. Some settings (I don't remember which) are really GPU hungry, try to identify them so you don't cause a huge GPU load for nothing.
My settings will not be optimal for you because of differences in display resolution and aspect ratio...and personal taste.
