Are you having trouble with your small ring not being "easy" enough? If that is not the case, then don't worry about it. A compact won't change things much and it doesn't really matter whether or not you are using both rings.
+1 Unless you feel that you NEED an easier gear to get up some hills, a compact won't matter to you. Just keep using your small ring and you will get stronger. My first months on a road bike were also mainly in the small ring.
