Hacking how do I know if everything on my system is up to date?

[MaGnUmKiLLa]

I have a softmodded wii and my question is how do I know I'm up to date with everything? I updated to 4.0 using that *ULTIMATE GUIDE* and before that I added the ios files needed to play games like madworld and animal crossing and I've updated certain cIOS files but I don't know if I'm up to date ya know? Heck, I'm not 100% that my HBC is up to date or not. So, can anyone help me out and tell me what all I should have and what version everything should be?

sorry if this is a n00b question
