Just download a 2.1 rom and reflash via odin. Since you have done it once already, you should know the trick

Reflashing will remove root.

I've done something similar except I didnt check what the original firmware was before I did it.

Whats a good basic one to use (for o2 in the uk)

Check samfirmware. I am not sure what the country code for UK is. You will have to find that out somewhere.
