Ok, so I wasn't off the mark with intent, just not fully understanding all the code.
The funny thing is, I did it yesterday and reinstalled 48 apps to be exact and when I went to the folder: /var/cache/apt/archive/
Only 2 deb files resided and they were nano and some other file which I think was associated to nano. So this doesn't seem to be the place it stores the archives?
Any other suggestions guys, I'm sorry I haven't a clue and you are doing your best though haven't an n900.
I hope I don't sound rude linuxeventually, I am very grateful, you are assisting me perfectly.
