How to retrieve apps after a complete iPod reset? The "App_Store Updates Purchase" tab isn't working!

Question

Hey Apple Community,
I have a problem, but every problem has a story, so let me explain that first.
Let's start of by saying that I bought my 32 Gb iPod in February, 2012.
Over the course of the last 21 monts there have been about 370+ different apps on it (not all at ones of course). Of which I purchased about 26. I should also mension that my iPod hasn't been Jailbreaked at any point of time (I just don't trust it).
Yesterday, I wanted to put some new songs and video's on it. So I connected my iPod to my PC (I use windows 8). When I opened, It told me that there was a new system update (iOS 6.1.5). Because I 'was' in a good mood and had the time, I pressed "Download and Install". The updates usually take some time to install so I minimalized iTunes and opened FireFox (to check my e-mail and watch some video's). About 8 minutes later, I got a notification from Windows telling me that iTunes had crashed. At that point the update wasn't done installing. I restarted my PC (just to be sure) and opened iTunes again. It immediately openened a notification, telling me that there was a damaged iPod connected to my PC. The only option I had was to restore it, which would mean that my iPod would get reset to it's manufacture settings. You can imagine that this sounded disturbing. Fortunately it also stated that I would get the option to restore it (to the way it was before the update/crash) after the reset. This would be done using the automated back-up system of iTunes. I started the reset and didn't touch my PC nor iPod until it was finished (just to be sure). Then I used the given 'restore to old state' option (the just installed version won't chance by doing this). After finishing, I immediately noticed that all of the apps that I installed were missing. In total about 100+ apps (about 60-70+ games, 30-40+ remaining apps). However I did get my photo's back (which are now backed up), that's nice! along with my music and video's. The missing apps are reinstallable but the saves aren't. Imagion 21 monts worth of game saves gone in a flash for more then 60 games. Of the 100+ app there are about 30 that I really want back, however I am unable the recall all of the names.
So I went into the App_Store > Updates > Purchased tab. Here comes the real problem. The purchase tab doesn't load, it isn't even displaying the choice to switch from 'all' to 'not on this device'. I've tried some things to get is to work again: restart my iPod, log out and back in my iOS accant (in the app store) and a combination of the last 2 things. This didn't work however.
My questions are:
1) Is this problem fixable? If yes, how?
2) If not, what would be the second best option of retrieving the missing apps?
Thanks before hand,
Sebgear

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings      
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:                                 
iOS: How to back up                                                                
- Restore to factory settings/new iOS device.             
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

Also, you should be able to redownload via iTunes on the computer. See that method included here:
