You can find the "Lenny" version of Debian here. If you have a high speed Internet connection available, I suggest downloading just the "business card" iso and installing everything else that you need across the Internet. You certainly don't want to download a full set of CDs or DVDs, there is way too much that you would never ever install there.

If you are uncomfortable about overwriting your MBR, see the dd command for a way to back it up to a file with Knoppix. You could then replace the original MBR if needed. Realize that this also copies the partition table (if you copy the full first sector, 256 bytes), so if you do repartition then you should make a new backup of the MBR. A Google search will quickly find several good examples of how to back up an MBR with dd.

You can also find the Debian website and way too many other Linux distros through Distrowatch.
