I had installed Ubuntu alongside Windows on a 40GB of 160 GB partition, deleted the Windows partition, even from the grub menu, as soon as i felt i could grope my way around. Since then i have upgraded to Jaunty, installed a ton of applications and even the Nvidia 185.19 Beta. I now wish to expand my present Ubuntu installation to occupy the entire disk. Sudo fdisk -l gives
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x556b556b

Device Boot Start End Blocks Id System
/dev/sda1 1 1275 10241406 83 Linux
/dev/sda2 1276 6374 40957717+ f W95 Ext'd (LBA)
/dev/sda3 6375 6605 1855507+ 83 Linux
/dev/sda5 1276 1667 3148708+ 7 HPFS/NTFS
/dev/sda6 1668 6175 36210478+ 83 Linux
/dev/sda7 6176 6374 1598436 82 Linux swap / Solaris

Now /dev/sda6 is my Ubuntu installation. I have tried booting from my live CD to use gparted, but the option to increase the partion size remains grayed out. Is there a way to clone just the Ubuntu install with all the upgrades, etc. and reinstalling it on my zero filled hard disk? I have a systemrescue CD but don't know what to do with it.

The trick of /var/cache/apt/archives worked on my laptop.

On a fresh install with full disk usage, Ubuntu creates two partitions one for all data and second for swap.

Mine looks like this:

Disk /dev/sda: 40.0 GB, 40007761920 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 4783 38419416 83 Linux
/dev/sda2 4784 4864 650632+ 5 Extended
/dev/sda5 4784 4864 650601 82 Linux swap / Solaris

In your case sda6, sda1, sda3 the heavyweight partitions and all marked as Linux partition.

So you may not need to repartition/format etc.
As you say the sda6 is Ubuntu partition, then you should be having a lot of disk space. If needed you just need to mount the sda1 and sda3 to a suitable folder, some area dedicated to music/video etc.

If you really keen on removing Windows partitions from disk then backup data and /var/cache/apt/archives to somewhere and then attempt fresh install.

For more detailed analysis you need to look at 'df -h' report.

I have already deleted the Windows partition, I thought i could use Roshan's tutorial to get all my software, upgrades (Jaunty), drivers and tweaks back after a reinstall of Intrepid from my live CD using the option "use entire disk".

As seen by the df -h results, your sda1 and sda3 are not mounted in filesystem.

For simple solution just mount at some useful place.

For elegant solution try Logical volume manager. It has some learning curve though.

I booted from a Live CD to use gparted, deleted the swap, because that was what was getting in the way, and just expanded sda6 all the way up
