I did reinstall the Operating System once so far, I'm always fiddling with things so it was all my own fault. For the latest install I used the new Noobs Installer, not a bad way to go for what I needed, it all worked perfectly. I will list the tutorials that helped me to install Sabnzbd and TransmissionBT. It's all been a great success, I might try XBMC on a Pi next...
Transmission installed on the Pi
I just found a decent tutorial on the web for installing Transmission, the following link served me well, of course you may need to tweak a few things, change a few paths etc.

Sabnzbd Installed on the Pi
Once again I searched for the appropriate "How to" online for installing Sabnzbd on the Raspberry Pi and once again you may need to tweak and adjut things for your install.

I will also list information on other needed software etc. I followed the tutorials above to set everything up, I also don't run the same settings on the Raspberry Pi as I would on a Desktop PC, I try not to stress the little Pi out too much.
