A bit late to this thread but I was working on vocals last night and thought I'd chime in.
90% of vocal quality, as the listener hears it, is going to come from the quality of the vocal performance and your mic technique, not from "pro gear." Listen to the album "Children of Desire" by Merchandise, it sounds like ass but the vocals are so confident that you don't notice after 5 seconds.
Your Rode is a totally acceptable mic, if you can I would recommend getting ahold of an above-average mic pre but definitely focus your time and effort on getting the right angle/distance from the mic, the right room placement, and singing like you mean it.
