There have been a lot of cios improvements since you modded your wii. Apparently you did find the need for ios 58 already and most likely have the newest homebrew channel running on it. Boot2...well, i think you know how lucky you are to have that! Some of the apps you have listed there are old or not needed to have on your card (cIOS38r14 installer,FCE Ultra GX channel installer,Snes GX/channel installer,Trucha bug restorer,WiiMC/channel installer,Priiloader_v0_2,IOS58 Installer). If you already installed the things from the installers then you don't really need to keep the installers. You mentioned starfall and you have priiloader in your apps, the 2 do not play well together. What I would recommend it to follow Mauifrog's softmod ANY wii guide (link is in my signature) to get yourself completely up to date on your softmod. It will install all the latest ios and cios and bring you up to system menu 4.1 which is the recommended system menu. It will get your priiloader up to date as well, and starfall will be removed. I don't know what version of usbloader gx you have but it has had a major facelift in the past year, I would update that too (do it manually, not online. we have a guide for it).
There is also the theory of If it aint broke , dont fix it. The choice is yours to make.
