Trying to get rid of redundant addons

[WeeBaby]

I am trying to clean up my addons and over the years I believe I have thrown in a few addons that are doing the same thing. Could someone tell me if the following addons are indeed basically the same and if anyone is better than another. I am wanting a addon that gives me as much info as possible as to where a itam comes from, how it helps me out, if I can buy it, etc. Any ideas or input would be awesome,
