Right firstly to upgrade your board make a backup of files and sql incase anything goes wrong (it shouldn't), just upload all the files from the new package, excluding conf_global.php.dist, overwriting the originals... the go to yourforum.com/admin/upgrade/ and run the script there, you may as well upload the new 1.1.1 shoutbox files before running the script and tick the box to upgrade that also....... let me know how you get on and i will cover some more of your requests later on

PS: If you don't have the newest files pm me and i will help you out.
