The stem/headset combo here is 1" threaded, so in order to swap out the stem, you would need to remove the bar tape and slide the bars out, etc.
As far as what geaering to run, that depends on a variety of things. Best thing to do is check out what the local runs and then ask/participate in a few classes to get your velo legs as well as some shared experience.
Enjoy - that looks to be a really nice bike for the track!
