It's your call wether you want to change it to static, give it a thought wether it's wise or not to. Static variables or methods consume less memory and I find them easy to use, which is why I use them often. I don't know if it's actualy faster.
As for dead code, you need to know for yourself. Maybe it's code that's currently not in use, but might be useful later. In this case commenting it out might be a good idea, or leave it be if you don't bother commening.
