1. Depends on how big the problem is but I never have had to. Usually just install, maybe you delete then reinstall.
PS. Never, NeVER NEVER install a firmware with a disk in. Ever.

2.Just like you said, use ban preventitive pkgs and luck. Be careful when playing on new CODs. If you want use a ftp to install anti ban eboots.

3.DOn't even go. You can get a download for anyting you want for free. Look into something called PSStuff or the new PSdl(newer, better version of PSStuff) Look for tuts and all your questions will be answered.

PS. Look into something called reactPSN.
