Fixed Hub and a Freewheel
I was wondering if there is any problem using a freewheel on a fixed hub. The threading on both are the same but the when the freewheel is put on some of the threads are still exposed. Is there any compromise to the integrity of the setup if it is like this?
Yes I know there are freewheel hubs, but the 120mm spacing of the track hub was the closest to that of my Raleigh of 114mm

Are you saying there's exposed threads between the hub and the freewheel or to the outside of the freewheel? If the exposed thread is on the hub side, then you have a problem with the threading, If the exposed thread is on the outside, then no problem.

The hub is a Surly Fixed/Fixed. I bought this based on the advice of Sheldon Brown who stated that freewheels could be used instead of fixed cogs as long in the lockring was left off. Currently, the freewheel is threaded on all the way but doesn't make contact with the threading for the lockring (since it is a smaller width). I can't imagine Sheldon suggesting this if it was a problem but I just some more opinions.

I have also heard that it's ok to do this (probably from Sheldon's site). In theory, since you can't apply back pressure when you have a freewheel, it's not a big deal that one or two threads aren't engaged. I would send an email to Surly to double check. In my experience they're pretty good about answering oddball questions.

I've got a few 120mm freewheel hubs (1979 Shimano 105s) if you need one:

It is definitely okay. I have the same setup on the non-fixie side of my fixie: Surly hub with freewheel on it. No problem. Don't worry about it; get out and ride!

You don't need a lockring with a freewheel, so it doesn't matter whether you see the lockring threads. As long as the freewheel is snugged up against the hub it is good.
