I have not really explored if any of these solutions to "eliminate" notifications works on the Samsung Tab but they all seem to suggest similar methods of stopping some unwanted notifications. There were originally posted for the Blackberry Playbook and then BB10 devices where some android apps run. I captured them and have used them. They are definitely redundant but each kind of expresses the same methods with slightly different language:
-----------------------
"I fixed my notifications by installing ghost commander from app world, then in the left pane chose apps, then found the downloads app, then chose "shortcuts" tapped the shortcut that appeared, launching the downloads app. From there I deleted the failed downloads and the notifications have stopped now. No need to uninstall any apps, unless they keep retrying the downloads even after deleting them manually.

Is it a download notification you are getting or some other app notification? The only ones I've had that have persisted are failed download ones, which I can fix using the method I described. Try launching the Android "Settings" app via Ghost Commander and see if you can find the app through the "Manage Applications" option there, to make sure it is definitely gone.
..............
A slightly easier method: Get "Quick App Manager" from the App World, run it and it should show icons for all Android apps. Tap "Downloads" (icon is a green square with a white downward arrow) and then "Open". From there delete the failed downloads.
Luckily, there's a fairly simple solution: Go to App World and download "Quick App Manager". Open this app, and it will show you all the Android apps installed on your PB, including a system app called "Downloads". Tap the "Downloads" app icon and choose to load the app, and you should find a list of files, probably just the two PDFs you mentioned. Tick the boxes beside them and delete them (can't remember if the option appears automatically when you tick the boxes or if you have to swipe down from the top bezel after ticking the boxes). That should fix your problem. Afterwards, you can delete Quick App Manager if you want.
...........
On the homescreen, you should see entries for Favorites, SD Card, PB Media, FTP, Windows Share, Applications, and Exit. Tap on "Applications". Then scroll down and tap on "Downloads". Then "Shortcuts", and then "Downloads-Main". From here, delete any entries that appear.

For BB10, too
Go to home screen of ghost commander and in that list there is an icon for applications. Click that icon, believe it's the second last one above the exit icon. When in application you will see a list of apps. Go to the app you want to edit the notification setting and press and hold it until option menu appears. Select manage from that menu. In there you can edit the settings.
