Glad to know you've lost the fear to mod, when I first did it I was about to wet my pants.
What you have to do is to use the JSGME. It's very nice app that allows you to enable a mod on top of your install in the order you prefer and if you don-t like what you ar eusing or what you did is not working, you can simply disenable it. Regarding your files, you have to take the time to compare them and see which one is the one you need.
Hope this helps, but in case you need more info, I am sure other kaleuns will give you more helpful advices.
