Yeah, you've got some old mods that should be removed.
For the 'Test Failed' I'd simple uninstall all of the mods, make sure all of their files are gone (except for any images) then upload all new smf files. Well, 'IF" you are going to get rid of the old ones. If they don't have an upgrade for the mods you'll probably always have errors. So, either you can deal with the errors, etc. or get rid of the old ones.
BTW, SMF will tell you to just ignore the db upgrade error.
