Increase home folder disk space ubuntu 11.10

Hello all,
I recently discovered ubuntu and I'm loving it. I'm planning to use it as my primary Os. My only problem now is that my home available disk space is less than 10GB and that really keeps me from working on large files. I worked on this for 3 days in vain. I burnt a gparted live CD but don't really know what to do with it(i.e which drive is windows and which one is ubuntu's...). Here what gparted window reads:

Partition File system mount Point Label Size

/dev/sda1 ntfs Recovery 9.00 GiB
/dev/sda2 ntfs System Reserved 100.00 MiB
/dev/sda3 ntfs host 456.67 GiB
unallocated unallocated 1.02 MiB

All I really want is a large home folder in ubuntu, like 200GB at least. Please help. I've heard of ext3, ext4 etc...And also i used wubi for the dual boot install.

Thank you...

partitioning

Have you backed up all your docs and are sure you want only Ubuntu? If so run the live CD find Gparted in the menus and the partitions I would recommend is / of 20GB ext4 -more than you need but very safe, swap of 4GB, and the rest in /Home also as ext4. If you are afraid of losing anything though don't do that as it will wipe all your data. In any case backup first!I backup to 2 different external hard drives.
