I agree with everyone else. Lower gearing will give you more control over the bike (once you get used to spinning fast) and better for the knees.
As for position on the bike, my road bike and fixed bike are set up as close to identical as I could get them, but I still mess with the fixed bike constantly. You do all sorts of pushing and pulling and shifting around on the saddle riding fixed that you don't do when you can shift and coast., so any fit/comfort problems are magnified.
