Essential softwares for Ubuntu

These are a list of softwares that I found very essential for Ubuntu.

1. Start-Up Manager
2. Compiz and Emerald
3. Ubuntu Tweaks
4. Gparted
5. Audacity
6. VLC
7. NTFS-3g
8. Nautilus Action Configuration
9. Nautilus Set as Wallpaper plugin

Synaptic download location

You could just mount the partition to "/var/cache/apt/archives". If you don't run "apt-get clean" the downloaded packages should stay there. I'd recommend doing a backup of the directory first, creating a new one and then mount the partition:
sudo mv /var/cache/apt/archives /var/cache/apt/archives_bk
sudo mkdir /var/cache/apt/archives
sudo mount /dev/sdXX /var/cache/apt/archives/
