This seems to be older than the versions available for my PC model on the Acer support page:

Would it be worthwhile for me to upgrade to the latest version? I'm a bit worried about the red text though, as this is something that I have also never done before. Although what's the worst thing that could happen? Another clean install? Or could it permanently brick the machine?
Looks like the top two updates, (2010/04/19 & 2010/06/28), were trying to fix problems with keyboards which may be what you experienced when going into BIOS.
If a BIOS update screws up then the machine becomes a brick unless it's fitted with Dual BIOS, (the second BIOS takes over in the case where the first becomes corrupt).
I've never had a problem doing a BIOS update, (which considering I live in a power outage prone area is almost a miracle), but if you're not comfortable with it you can always grab the machine, a copy of the BIOS update, and take them down to the local computer shop and get them to perform it.
All manufacturers give a warning notice regarding BIOS updates, it's part of their CYA policy.That said, if you're not experiencing any problems in your day-to-day use of the computer that would be fixed by doing the BIOS update, then don't consider it a necessity that needs to happen.
I just did a BIOS update on mine within the last few days, it was three versions behind, it wasn't to fix anything on my machine, (just added support for CPUs I'll never have) - I just don't like being that far out of sync with the latest update ... it's a techie thing
Can I still use my AOMEI Backupper system image to selectively restore certain software to the Program Files and some of my data folders (My Documents and User)? Or is that not possible or advisable?
I also have copies of these folders on an external drive, so I could also just drag and drop them back in their place. Or would that mess things up?
Or is it best to reinstall software from scratch, and then drag and drop the "My Documents" data for them?
You need to reinstall software from scratch, unless they're portable programs, in which case just copy them across to wherever you want them. Documents can be copied across to your new Documents/Pictures/Videos/Music/etc folders.
If you want to copy them from the backup image, install AOMEI Backupper, then under one of the options down the left side, (I think it's Utilities(?) - don't have it installed at the moment), you have the option to Mount (could be Explore) an image. Selecting that will let you choose your backup image which the program will then mount under a drive letter so you can access it through Explorer or some other file manager.
