ITunes 10.5 won't really sync iOS 5 iPod touch 3g

Question

Hi,
I have recently upgraded my iPod touch 3g to iOS5.
Now I face nothing but problems.
The problem I would like to discuss here is following:
iTunes 10.5.0.142 on Windows 7 Home Premium
iPod touch 3g with iOS5.0.
When I synchronize 1 or more apps the apps appear on the iTunes app window, but not on the iPod itself.
When I delete an app on iTunes and synchronize, the app disappears from the iTunes app window, but not on the iPod itself.
So, even if you would think a real sync it taken place, it is just a bogus sync, or at most an iTunes internal sync.
Only when I sync music or a book, then it really syncs.
This means that in principle everything is okay.
In fora I see a lot of sync issues, but did not came across this one yet.
Other problem I have is:
App Store crashes all the time.
It starts, says Loading... and then crahses after a few seconds.
Some say that if you download 1 free app it will solve some problems (like other apps crashing at once), but I cannot get to the point of downloading an app.
And when downloading an app via iTunes, I run into my not-really-syncing problem.
I have hard-resetted the iPod several times.
I have re-installed iOS5.
I also tried to down-grade to iOS 4.3.5 but that fails on error message 3194.
All suggestion for solving that problem did not help.
The iPod is prety useless at this moment, except for listening music.
I also have an iPad 1 running on iOS5 and there I have no problems at all.
Any advice is welcome.
Greetings,
ejdv

Unsupported is the official line so any help would be use your own sleuthing skill to find a how to article and what you need to do to get 4.3.x back and restored - of course backups of everything - AppData, iTunes media - whatever you can.
However.... there are apps that are not iOS 5 friendly or not iTunes 10.5.
If you see "Other" as more than a fraction of GB then likely need to restore the device completely, corrupt data or whatever.
Might want to wait for a bug fix on all this too.
I got iOS 5 finally after a lost week of less sleep and more frustration, only to run into an issue and ended up with the iPod (month old 4G) deciding I was getting a complete restore for some reason - and can't use for today.
I had one app I liked, got an update, and that was when I found that they had not tested to insure it would still work with iOS 4.3.5. It depends on Newstand, and would not sync or allow it to be moved, nothing at all under 4.3.5.
Found a couple others now too.
but can't know with 100% without a "clean" install of everything: iOS, iTunes, Windows also.
