If you have "extra" components, might as well run them. If/when you find that they are holding you back, you can then buy the best part to take care of that difficiency.
You might also find out you want different length cranks then on your road bike, if you bought a track specific version right now which matches your road stuff, you will then have extra track components when you buy the new stuff.
