Ipod Touch: My Issues, help needed as fast as possible

Question

Well recently i got an Ipod Touch 2nd Generation for christmas, and i must say i love it. But i have got some serious problems. 1) all applications that were not standard on the itouch crash unexpectedly and the only way to rectify this issue is to download something from the app store and they work again :S. Yes that is as bizarre as it sounds. Sometimes it will work fine and i can use any of my apps whenever i like. But frequently(more frequently as time goes on) the applications dont open, i touch them they open the background for the app and they take me back to the main screen. I have tried the following: reseting the iPod, restoring it to factory settings, uninstalling apps and then re-installing and this issue is resolute. I also happen to know that some other 2nd Generation Touch owners at my school have the very same issue. I have seen some threads dotted about explaining their issues that are similar to this, meaning its fairly widespread.
My second issue is really bugging me, i opened the itunes store for the first time on my iPod(i never get any of my music from itunes normally i detest the application.) and all of a sudden it downloaded a podcast without me telling it to. It was called Podhead: The DoorWhores Off to vegas. This is something i really do not wish to have on my iPod. So i synced it to my windows OS and tried to re-sync the iPod's podcasts with my library so that it would dissappear. But it didn't, i then tried setting it to manually putting files on my ipod and alas it doesnt show up in the podcasts sub section of the device. I tried playing the podcast and it takes me to the home screen of my ipod with the Play triangle flickering constantly in the top right of my ipod. I don't know what is going on with that but i havnt restored it to factory settings after this issue, mainly because my iPod refuses to accept that i own all of the apps i have backed up and i have no desire to manually re-download them to my ipod.
3) That last scentence brings me nicely onto my final problem which is this: my computer tells me that i do not have the authority to put onto my ipod. Despite all of them being free and despite all of them having being backed up from my ipod.
Any help with these issues would be much appreciated. I am in desperate need of assistance before i come to the end of my tether and resign myself to a long trip to the nearest apple store. thanks in advance

Did you try to restore your iPod to factory settings and add your apps one by one to find out which app causes the crash? Try not to restore from a backup it may contain the corrupt parts you don't want to install again.

Deauthorize and authorize your computer in iTunes, here's how to:
