Yes, it's likely to help as long as the savedata is uploaded to PS Plus before the corruption happens. It's a good idea to disable the auto-upload feature if you're worried about corrupted data being saved to the cloud.
I haven't experienced any savedata corruption, but I assume that corrupted savedata would be uploaded to the cloud too as the cloud wouldn't actually know if the data is corrupted. Hopefully, the PS4 safeguards against this by not uploading corrupted data to start with.
One: You can back up save files and then restore them at a later time even to another account. If you are a PS+ member you can back them up to a server and they will be linked to your PSN. However in your case, you'll probably want to back them up manually, which can be done as so:
- On the XMB (cross media bar), go to the Game section.
- Go to Game Saves
- Put in your memory stick (cf, ms duo, sd)
- Find the game save you want to copy/backup, highlight it and hit the Triangle button.
- Choose the menu option to Copy
- Hit the X button on the memory stick and let it copy.

It should be noted that some games use copy-prevention methods to, well, prevent copying. However, it's still possible to back even those games up. Google is your friend here.
Two: I'm surprised the previous owner's PSN is still on there, but yes you could use his DLC, as long as his PSN remains registered on the console (so don't delete his User account.) Off the top of my head I don't know how this will affect trophies. You should still be able to earn DLC trophies, but they might register for the owner of the original purchase. (The PS Vita has this problem.)
Three: The PS3 is not region locked for games, so you should be able to play everything fine. However, I do believe the Playstation Store is region based, and so some content will only be available depending on which region's store you access. I'm not sure if this is determined by the console (e.g. a US PS3 vs. a JP PS3) or registered PSN region. Also, you may have some conflict if trying to purchase content that is normally not available in your region.
I hope this helps!
P.S. Congrats on the new PS3!

They do stack.
If you have a look at the expiration date for any PS Plus content you've downloaded, you'll see it has been expanded by 1 year exactly.
On PS3, navigate to any PS Plus game, press
, select

Information, then scroll down toValid Period (End)or toRemaining Time.On PS Vita, touch and hold any PS Plus game, select
Information, and seeExpiresorRemaining Time.Due to DDoS attacks taking down SEN in December, Sony has decided to gift 5 days of PS Plus to whomever had a valid subscription in 2014-12-25 (December 25 of 2014). Because of that, it is possible the expiration date for your game may have been extended by a year and 5 days.
