"1) What programs/widgets are there that will on saving and backing up, Password XXXXX Documents, photos, movies and music ."
So you are asking what programs are out there that will password XXXXX all of your items? I'm not entirely sure what you are asking, so here'a a couple of answers:
There's several backup options for you. Since you are using 10.5, the built-in Time Machine is a good "set it and forget it" approach. For making bootable backups, SuperDuper and CarbonCopyCloner are good choices. SuperDuper costs about $28 US (http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html) and CarbonCopyCloner is free (http://www.bombich.com/software/ccc.html)
It sounds like you are asking about password XXXXX for lots of files rather than just a few. Please look into FileVault, though I caution you: lose your password XXXXX you are completely sunk. FileVault, built into the mac, allows you to encrypt your data making it inaccessible to anyone without access. It's not exactly for the faint of heart and extra precautions should be taken.
2)I got a auto-prompt from Apple saying here was an OSX update for my to 10.5.7, the size was quite big to download at over 400mb. I downloaded the update and was prompted to restart the computer, which I did. I the got the following prompt from the computer,
You asked why your computer would do this when all other updates went well...there have been a lot of reports of the 10.5.7 update having download/installation issues, so most likely it is not an issue with your computer at all.
I'd suggest getting the stan-alone installer and trying to update it that way, just bypassing the Software Update tool. The version you download will depend on if you are running OS X 10.5.0 - 10.5.4 or if you are running 10.5.5 - 10.5.6.
If you are usng a pre-10.5.5 version of Leopard, you can get the combo updater.
